ISP1760
Hi-Speed Universal Serial Bus host controller for embedded applications
Rev. 01 — 8 November 2004 Product data sheet

1. General description

The ISP1760 is a Hi-Speed Universal Serial Bus (USB) Host Controller with a generic processor interface. It integrates one Enhanced Host Controller Interface (EHCI), one Transaction Translator (TT) and three transceivers. The Host Controller portion of the ISP1760 and thethree transceivers comply to The EHCI portion of the ISP1760 is adapted from
Specification for Universal Serial Bus Rev. 1.0
The integrated high-performance Hi-Speed USB transceivers enable the ISP1760 to handle all Hi-Speed USB transfer speed modes: high-speed (480 Mbit/s), full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s). The three downstream ports allow simultaneous connection of three devices at different speeds (high-speed, full-speed and low-speed).
The generic processor interface allows the ISP1760 to be connected to various processors as a memory-mapped resource. The ISP1760 is a slave host: it does not require ‘bus-mastering’ capabilities of the host system bus. The interface is configurable, ensuring compatibility with a variety of processors. Data transfer can be performed on 16 bits or 32 bits, using Programmed Input/Output (PIO) or Direct Memory Access (DMA) with major control signals configurable as active LOW or active HIGH.
Universal Serial Bus Specification Rev. 2.0
.
.

2. Features

Integration of the TT allows connection to full-speed and low-speed devices, without the need of integrating Open Host Controller Interface (OHCI) or Universal Host Controller Interface (UHCI). Instead of dealing with two sets of software drivers—EHCI and OHCI or UHCI—you need to deal with only one set—EHCI—that dramatically reduces software complexity and IC cost.
The Host Controller portion of the ISP1760 complies with
Specification Rev. 2.0
The EHCI portion of the ISP1760 is adapted from
Specification for Universal Serial Bus Rev. 1.0
Contains three integrated Hi-Speed transceivers that support the high-speed,
full-speed and low-speed modes
Integrates a TT for Original USB (full-speed and low-speed) device support
Up to 64-kbyte internal memory (8kx64bits) accessible through a generic processor
interface; operation in multitasking environments is made possible by the implementation of virtual segmentation mechanism with bank switching on task request

3. Applications

The ISP1760 can be used to implement a Hi-Speed USB compliant Host Controller connected to most of the CPUs present in the market today, having a generic processor interface with demultiplexed address and data bus. This is because of the efficient slave-type interface of the ISP1760.
The internal architecture of the ISP1760 is such that it can be used in a large spectrum of applications requiring a high-performance internal Host Controller.

3.1 Examples of a multitude of possible applications

Set-top box: for connecting external high-performance mass storage devices
Mobile phone: for connecting various USB devices
Personal Digital Assistant (PDA): for connecting a large variety of USB devices
Printer: for connecting external memory card readers, allowing direct printing
Digital Still Camera (DSC): for printing to an external USB printer, for direct printing
Mass storage: for connecting external memory card readers or other mass storage
devices, for direct back-up. The low power consumption and deep power management modes of the ISP1760
make it particularly suitable for use in portable devices.

7. Functional description

7.1 ISP1760 internal architecture:Advanced Philips Slave Host Controller and hub

The EHCI block and the Hi-Speed USB hub block are the main components of the Advanced Philips Slave Host Controller.
The EHCI is the latest generation design, with improved data bandwidth. The EHCI in the ISP1760 is adapted from
Serial Bus Rev. 1.0
The internal Hi-Speed USB hub block replaces the companion Host Controller block used in the original PCI Hi-Speed USB Host Controllers to handle the full-speed and low-speed modes. The hardware architecture in the ISP1760 is simplified to help reduce cost and development time, by eliminating the additional work involved in implementing the OHCI software required to support the full-speed and low-speed modes.
Figure 3 shows the internal architecture of the ISP1760. The ISP1760 implements the
EHCI that has an internal port—the Root Hub port (not availableexternally)—on which the internal hub is connected. The three external ports are always routed to the internal hub. The internal hub is a Hi-Speed USB (USB 2.0) hub including the TT.
ISP1760
Embedded Hi-Speed USB host controller
Enhanced Host Controller Interface Specification for Universal
.
Remark: The root hub must be enabled and the internal hub must be enumerated. Enumerate the internal hub as if it is externally connected. For details, refer to
Linux Programming Guide (AN10042)
At the Host Controller reset and initialization, the internal Root Hub port will be polled until a new connection is detected, showing the connection of the internal hub.
The internal Hi-Speed USB hub is enumerated using a sequence similar to a standard Hi-Speed USB hub enumeration sequence, and the polling on the Root Hub is stopped because the internal Hi-Speed USB hub will never be disconnected. When enumerated, the internal hub will report the three externally available ports.

7.2 Host Controller buffer memory block

7.2.1 General considerations
The internal addressable Host Controller buffer memory is 63 kbytes. The 63-kbyte effective memory size is the result of subtracting the size of registers (1 kbyte) from the total addressable memory space defined in the ISP1760 (64 kbytes).This is the optimized value for achieving the highest performance with a minimal cost.
The ISP1760 is a slave Host Controller. This means that it does not need access to the local bus of the system to transfer data from the memory of the system to the ISP1760 internal memory, unlike the case of the original PCI Hi-Speed USB Host Controllers. Therefore, correct data must be transferred to both the Philips Transfer Descriptor (PTD) area and the payload area by Parallel I/O (PIO) (CPU access) or programmed DMA.
The ‘slave-host’ architecture ensures better compatibility with most of the processors present in the market today because not all processors allow a ‘bus-master’ on the local bus. It also allows better load balancing of the processor’s local bus because only the internal bus arbiter of the processor controls the transfer of data dedicated to USB. This preventsthe local bus from being busy when other more important transfersmay be in the queue; and therefore achieving a ‘linear’ system data flow that has less impact on other processes running at the same time.

The considerations mentioned are also the main reason for implementing the prefetching technique, instead of using a READYsignal. The resulting architecture avoids ‘freezing’ of the local bus (by asserting READY), enhancing the ISP1760 memory access time, and avoiding introduction of programmed additional wait states. For details, see Section 7.3 and Section 8.3.8.

The total amount of memory allocated to the payload determines the maximum transfer size specified by a PTD—a larger internal memory size results in less CPU interruption for transfer programming. This means less time spent in context switching, resulting in better CPU usage.
A larger buffer also implies a larger amount of data can be transferred. The transfer, however, can be done over a longer period of time, to maintain the overall system performance. Each transfer of the USB data on the USB bus can span for up to a few milliseconds before requiring further CPU intervention for data movement.
The internal architecture of the ISP1760 allows a flexible definition of the memory buffer for optimization of the data transfer on the CPU extension bus and the USB. It is possible to implement various data transfer schemes, depending on the number and type of USB devices present (for example: push-pull—data can be written to half of the memory while data in the other half is being accessed by the Host Controller and sent on the USB bus). This is useful especially when a high-bandwidth ‘continuous or periodic’ data flow is required.
Through an analysis of the hardware and software environment regarding the usual data flow and performance requirements of most embedded systems, Philips has determined the optimal size for the internal buffer as approximately 64 kbytes.
ISP1760
Embedded Hi-Speed USB host controller
7.2.2 Structure of the ISP1760 Host Controller memory
The 63-kbyte internal memory consists of the PTD area and the payload area. Both the PTD and payload memory zones are divided into three dedicated areas for each
main type of USB transfer: isochronous (ISO), interrupt (INT) and Acknowledged Transfer List (ATL). As shown in Table 3, the PTD areas for ISO, INT and ATL are grouped at the beginning of the memory, occupying the address range 0400h to 0FFFh, following the address space of the registers. The payload or data area occupies the next memory address range 1000h to FFFFh, meaning that 60 kbytes of memory are allocated for the payload data.
A maximum of 32 PTD areas and their allocated payload areas can be defined for each type of transfer. The structure of a PTD is similar for every transfer type and consists of eight Double Words (DWs) that must be correctly programmed for a correct USB data transfer. The reserved bits of a PTD must be set to logic 0. A detailed description of the PTD structure can be found in Section 9.
The transfer size specified by the PTD determines the contiguous USB data transfer that can be performed without any CPU intervention. The respective payload memory area must be equal to the transfer size defined. The maximum transfer size is flexible and can be optimized, depending on the number and nature of USB devices or PTDs defined and their respective MaxPacketSize.
The CPU will program the DMA to transfer the necessary data in the payload memory. The next CPU intervention will be required only when the current transfer is completed and DMA programming is necessary to transfer the next data payload. This is normally signaled by the IRQ that is generated by the ISP1760 on completing the current PTD, meaning all the data in the payload area was sent on the USB bus. The external IRQ signal is asserted according to the settings in the IRQ Mask OR or IRQ Mask AND registers, see Section 8.4.

The RAM is structured in blocks of PTDs and payloads so that while the USB is executing on an active transfer-based PTD, the processor can simultaneously fill up another block area in the RAM. A PTD and its payload can then be updated on-the-fly without stopping or delaying any other USB transaction or corrupting the RAM data.
Some of the design features are:
The address range of the internal RAM buffer is from 0400h to FFFFh.
The internal memory contains isochronous, interrupt and asynchronous PTDs, and
respective defined payloads.
All accesses to the internal memory are double-word aligned.
Internal memory address range calculation:
Memory address = (CPU address – 0400h) (shift right >> 3). Base address is 0400h.

Both the CPU interface logic and the USB Host Controller require access to the internal ISP1760 RAM at the same time. The internal arbiter controls these accesses to the internal memory, organized internally on a 64-bit data bus width, allowing a maximum bandwidth of 240 MB/s. This bandwidth avoids any bottleneck on accesses both from the CPU interface and the internal USB Host Controller.

7.3 Accessing the ISP1760 Host Controller memory: PIO and DMA

The CPU interface of the ISP1760 can be configured for a 16-bit or 32-bit data bus width. When the ISP1760 is configured for a 16-bit data bus width, the upper unused 16 data lines must be pulled up to V together to a single 10 k pull-up resistor. The 16-bit or 32-bit data bus width configuration is done by programming bit 8 of the HW Mode Control register. This will determine the register and memory access types in both PIO and DMA modes to all internal blocks: Host Controller, Peripheral Controller and OTG Controller. All accesses must be word-aligned for 16-bit mode and double-word aligned for 32-bit mode, where one word = 16 bits. When accessing the Host Controller registers in 16-bit mode, the

. This can be achieved by connecting DATA[31:16] lines
CC(I/O)
Page 17
Philips Semiconductors
register access must alwaysbe completed using two subsequent accesses. In the case of a DMA transfer, the 16-bit or 32-bit data bus width configuration will determine the number of bursts that will complete a certain transfer length.
In PIO mode, CS_N, WR_N and RD_N are used to access registers and memory. In DMA mode, the data validation is performed by DACK—instead of CS_N—together with the WR_N and RD_N signals. The DREQ signal will always be asserted as soon as the ISP1760 DMA is enabled, as described in the following section.
7.3.1 PIO mode access—memory read cycle
The following method has been implemented to reduce the read access timing in the case of a memory read:
The Memory register contains the starting address and the bank selection to read
from the memory. Before every new read cycle of the same or different banks, an appropriate value is written to this register.
Once a value is written to this register, the address is stored in the FIFO of that bank
and is then used to prefetch data for the memory read of that bank. For every subsequent read operation executed at a contiguous address, the address
pointer corresponding to that bank is automatically incremented to prefetch the next data to be sent to the CPU.
Memory read accesses for multiple banks can be interleaved. In this case, the FIFO block handles the MUXing of appropriate data to the CPU.
The address written to the Memory register is incremented and used to successively
prefetch data from the memory irrespective of the value on the address bus for each bank, until a new value for a bank is written to the Memory register.
For example, consider the following sequence of operations:
Write the starting (read) address 4000h and bank1 = 01 to the Memory register.
Write the starting (read) address 4100h and bank2 = 10 to the Memory register.
ISP1760
Embedded Hi-Speed USB host controller
When RD_N is asserted for three cycles with A[17:16] = 01, the returned data corresponds to addresses 4000h, 4004h and 4008h.
Remark: Once 4000h is written to the Memory register for bank1, the bank select value determines the successive incremental addresses used to fetch the data. That is, the fetching of data is independent of the address on A[15:0] lines.
When RD_N is asserted for four cycles with A[17:16] = 10, the returned data corresponds to addresses 4100h, 4104h, 4108h and 410Ch.
Consequently, the RD_N assertion with A[17:16] = 01 will return data from 400Ch because the bank1 read stopped there in the previous cycle. Also, RD_N assertions with A[17:16] = 010 will now return data from 4110h because the bank2 read stopped there in the previous cycle.
7.3.2 PIO mode access—memory write cycle
The PIO memory write access is similar to a normal memory access. It is not necessary to set the prefetching address before a write cycle to the memory.
The ISP1760 internal write address will not be automatically incremented during consecutive write accesses, unlike in a series of ISP1760 memory read cycles. The memory write address must be incremented before every access.

7.3.3 PIO mode access—register read cycle
The PIO register read access is similar to a general register access. It is not necessary to set a prefetching address before a register read.
The ISP1760 register read address will not be automatically incremented during consecutive read accesses, unlike in a series of ISP1760 memory read cycles. The ISP1760 register read address must be correctly specified before every access.
7.3.4 PIO mode access—register write cycle
The PIO register write access is similar to a general register access. It is not necessary to set a prefetching address before a register write.
The ISP1760 register write address will not be automatically incremented during consecutive write accesses, unlike in a series of ISP1760 memory read cycles. The ISP1760 register write address must be correctly specified before every access.
7.3.5 DMA—read and write operations
The internal ISP1760 Host Controller DMA is a slave DMA. The host system processor or DMA must ensure the data transfer to or from the ISP1760 memory.
ISP1760
Embedded Hi-Speed USB host controller
The ISP1760 DMA supports a DMA burst length of 1, 4, 8 and 16 cycles forboth the 16-bit and 32-bit data bus width. DREQ will be asserted at the beginning of the first burst of a DMA transfer and will be deasserted on the last cycle (RD_N or WR_N active pulse) of that burst. It will be reasserted shortly after the DACK deassertion, as long as the DMA transfer counter was not reached. DREQ will be deasserted on the last cycle when the DMA transfer counter is reached and will not reasserted until the DMA reprogramming is performed. Both the DREQ and DACK signals are programmable as active LOW or active HIGH, according to the system requirements.
The DMA start address must be initialized in the respective register, and the subsequent transfers will automatically increment the internal ISP1760 memory address. A register or memory access or access to other system memory can occur in between DMA bursts, whenever the bus is released because DACK is deasserted, without affecting the DMA transfer counter or the current address.
Any memory area can be accessed by the system’sDMA at any starting address because there are no predefined memory blocks. The DMA transfer must start on a word or Double Word address, depending on whether the data bus width is set to 16 bit or 32 bit. DMA is the most efficient method to initialize the payload area, to reduce the CPU usage and overall system loading.
The ISP1760 does not implement EOT to signal the end of a DMA transfer. If programmed, an interrupt may be generated by the ISP1760 at the end of the DMA transfer.
The slave DMA of the ISP1760 will issue a DREQ to the DMA controller of the system to indicate that it is programmed for transfer and data is ready. The system DMA controller may also start a transfer without the need of the DREQ, if the ISP1760 memory is available for the data transfer and the ISP1760 DMA programming is completed.

Page 19
Philips Semiconductors
It is also possible that the system’s DMA will perform a memory-to-memory type of transfer between the system memory and the ISP1760 memory. The ISP1760 will be accessed in the PIO mode. Consequently, memory read operations must be preceded by initializing the Memory register (address 033Ch), as described in Section 7.3.1. No IRQ will be generated by the ISP1760 on completing the DMA transfer but an internal processor interrupt may be generated to signal that the DMA transfer is completed. This is mainly useful in implementing the double-buffering scheme for data transfer to optimize the USB bandwidth.
The ISP1760 DMA programming involves:
Set the active levels of signals DREQ and DACK in the HW Mode Control register.
The DMA Start Address register contains the first memory address at which the data
transfer will start. It must be word-aligned in the 16-bit data bus mode and double word aligned in the 32-bit data bus mode.
The programming of the DMA Configuration register specifies:
The type of transfer that will be performed: read or writeThe burstsize—expressed in bytes—is specified, regardless of the data bus width.
The transferlength—expressed in number of bytes—defines the number of bursts.
Enable ENABLE_DMA (bit 1) of the DMA Configuration register to determine the
ISP1760
Embedded Hi-Speed USB host controller
For the same burst size, a double number of cycles will be generated in the 16-bit mode data bus width as compared to the 32-bit mode.
The DREQ will be deasserted and asserted to generate the next burst, as long as there are bytes to be transferred. At the end of a transfer, the DREQ will be deasserted and an IRQ can be generated if DMAEOTINT (bit 3 in the Interrupt register) is set. The maximum DMA transfersize is equal to the maximum memory size. The transfer size can be an odd or even number of bytes, as required. If the transfer size is an odd number of bytes, the number of bytes transferred by the system’s DMA is equal to the next multiple of two for the 16-bit data bus width or four for the 32-bit data bus width. For a write operation, however, only the specified odd number of bytes in the ISP1760 memory will be affected.
assertion of DREQ immediately after setting the bit.
After programming the preceding parameters, the system’sDMA maybe enabled (waiting for the DREQ to start the transfer or immediate transfer may be started).
The programming of the system’s DMA must match the ISP1760 DMA parameters programmed above. Only one DMA transfer may take place at a time. A PIO mode data transfer may occur simultaneously with a DMA data transfer, in the same or a different memory area.

7.4 Interrupts

The ISP1760 will assert an IRQ according to the source or event in the Interrupt register. The main steps to enable the IRQ assertion are:
1. Set GLOBAL_INTR_EN (bit 0) in the HW Mode Control register.
2. Define the IRQ active as levelor edge in INTR_LEVEL (bit 1) of the HW Mode Control register.

Product data sheet Rev. 01 — 8 November 2004 19 of 105
Page 20
Philips Semiconductors
3. Define the IRQ polarity as active LOW or active HIGH in INTR_POL (bit 2) of the HW Mode Control register. These settings must match the IRQ settings of the host processor.
By default, interrupt is level-triggered and active LOW.
4. Program the individual interrupt enable bits in the Interrupt Enable register. The software will need to clear the interrupt status bits in the Interrupt register before enabling individual interrupt enable bits.
Additional IRQ characteristics can be adjusted in the Edge Interrupt Count register, as necessary, applicableonly when IRQ is set to be edge-active (a pulse of a defined width is generated every time IRQ is active).
Bits 15 to 0 of the Edge Interrupt Count register define the IRQ pulse width. The maximum pulse width that can be programmed is FFFFh, corresponding to a 1 ms pulse width. This setting is necessary for certain processors that may require a different minimum IRQ pulse width than the default value. The default IRQ pulse width set at power on is approximately 500 ns.
Bits 31 to 24 of the Edge Interrupt Count register define the minimum interval between two interrupts to avoid frequent interrupts to the CPU. The default value of 00h attributed to these bits determines the normal IRQ generation, without any delay. When a delay is programmed and the IRQ becomes active after the respective delay, several IRQ events may have already occurred.
ISP1760
Embedded Hi-Speed USB host controller
All the interrupt events are represented by the respective bits allocated in the Interrupt register. There is no mechanism to show the order or the moment of occurrence of an interrupt.
The asserted bits in the Interrupt register can be cleared by writing back the same valueto the Interrupt register. This means that writing logic 1 to each of the set bits will reset the corresponding bits to the initial inactive state.
The IRQ generation rules that apply according to the preceding settings are:
If an event of interrupt occurs but the respective bit in the Interrupt Enable register is
not set, then the respective Interrupt register bit is set but the interrupt signal is not asserted.
An interrupt will be generated when interrupt is enabled and the respective bit in the Interrupt Enable register is set.
For a level trigger, an interrupt signal remains asserted until the processor clears the
Interrupt register by writing logic 1 to clear the Interrupt register bits that are set.
If an interrupt is made edge-sensitive and is asserted, writing to clear the Interrupt
register will not have any effect because the interrupt will be asserted for a prescribed amount of clock cycles.
The clock stopping mechanism does not affect the generation of an interrupt. This is
useful during the suspend and resume cycles, when an interrupt is generated to signal a wake-up event.
The IRQ generation can also be conditioned by programming the IRQ Mask OR and IRQ Mask AND registers. Setting some of the bits in these registers to logic 1 will determine the IRQ generation only when the respective AND or OR conditions of completing the respective PTDs is met.

Page 21
Philips Semiconductors
With the help of the IRQ Mask AND and IRQ Mask OR registers for each type of transfer—ISO, INT and bulk—software can determine which PTDs get priority and an interrupt will be generated when the AND or OR conditions are met. The PTDs that are set will wait until the respective bits of the remaining PTDs are set and then all PTDs generate an interrupt request to the CPU together.
The registers definition shows that the AND or OR conditions are applicable to the same category of PTDs—ISO, INT, ATL.
When an IRQ is generated, the PTD Done Map registers and the respective V bits will show which PTDs were completed.
The rules that apply to the IRQ Mask AND or IRQ Mask OR settings are:
TheOR mask has a higher priority over the AND mask. An IRQ is generated if bit n of
the done map is set and the corresponding bit n of the OR Mask register is set.
If the OR mask for any done bit is not set, then the AND mask comes into picture. An
IRQ is generated if all the corresponding done bits of the AND Mask register are set. For example: If bits 2, 4 and 10 are set in the AND Mask register, an IRQ is generated only if bits 2, 4, 10 of the done map are set.
If using the IRQ interval setting for the bulk PTD, an interrupt will only occur at the
regular time interval as programmed in the ATL Done Timeout register. Even if an interrupt event occurs before the timeout of the register, no IRQ will be generated until the time is up.
ISP1760
Embedded Hi-Speed USB host controller
For an example on using the IRQ Mask AND or IRQ Mask OR registers without the ATL Done Timeout register, see Table 4.
The AND function: Activate the IRQ only if PTDs 1, 2 and 4 are done. The OR function: If any of the PTDs 7, 8 or 9 are done, an IRQ for each of the PTD will be
raised.

7.5 Phase-Locked Loop (PLL) clock multiplier

The internal PLL requires a 12 MHz input, which can be a 12 MHz crystal or a 12 MHz clock already existing in the system with a precision better than 50 ppm. This allows the use of a low-cost 12 MHz crystal that also minimizes Electro-Magnetic Interference (EMI). When an external crystal is used, make sure the CLKIN pin is connected to V

The PLL block generates all the main internal clocks required for normal functionality of various blocks: 30 MHz, 48 MHz and 60 MHz.
No external components are required for the PLL operation.

7.6 Power management

The ISP1760 implements a flexible power management scheme, allowing various power saving stages.
The usual powering scheme implies programming EHCI registers and the internal Hi-Speed USB (USB 2.0) hub in the same way it is done in the case of a PCI Hi-Speed USB Host Controller with a Hi-Speed USB hub attached.
When the ISP1760 is in suspend mode, the main internal clocks will be stopped to ensure minimum power consumption. An internal LazyClock of 100 kHz ± 40 % will continue running. This allows initiating a resume on one of the following events:
External USB device connect or disconnect
Assertion of the CS_N signal because of any access to the ISP1760
Driving the SUSPEND/WAKEUP_N pin to a LOW level.
ISP1760
Embedded Hi-Speed USB host controller
The SUSPEND/WAKEUP_N pin is a bidirectional pin. This pin should be connected to one of the GPIO pins of a processor.
The awake state can be verified by reading the LOW level of this pin. If the level is HIGH, it means that the ISP1760 is in the suspend state.
The SUSPEND/WAKEUP_N pin requires a pull-up because in the ISP1760 suspended state the pin becomes three-state and can be pulled down, driving it externally by switching the processor’s GPIO line to the output mode to generate the ISP1760 wake-up.
The SUSPEND/WAKEUP_N pin is a three-state output. It is also an input to the internal wake-up logic.
When in suspend mode, the ISP1760 internal wake-up circuitry will sense the status of the SUSPEND/WAKEUP_N pin:
If it remains pulled-up, no wake-up is generated because a HIGH is sensed by the
internal wake-up circuit.
If the pin is externally pulled LOW (for example, by the GPIO line or just as a test by
jumper), the input to the wake-up circuitry becomes LOW and the wake-up is internally initiated.
The resume state has a clock-off count timer defined by bits 31 to 16 of the Power Down Control register. The default value of this timer is 10 ms, meaning that the resume state will be maintained for 10 ms. If during this time, the RUN/STOP bit in the USBCMD register is set to logic 1, the Host Controller will go into a permanent resume—the normal functional state. If the RUN/STOP bit is not set during the time determined bythe clock-off count, the ISP1760 will switch back to suspend mode after the specified time. The maximum delay that can be programmed in the clock-off count field is approximately 500 ms.

Philips Semiconductors
Additionally, the Power Down Control register allows the ISP1760 internal blocks to be disabled for lower power consumption as defined in Table 5.
The lowest suspend current that can be achieved is approximately 100 µA at room temperature. The suspend current will increase with the increase in temperature, with approximately 300 µA at 40 °C and up to a typical 1 mA at 85 °C. The system is not in suspend mode when its temperature increases above 40 °C. Therefore, even a 1 mA current consumption by the ISP1760 (in suspend mode) can be considered negligible. In normal environmental conditions, when the system is in suspend mode, the maximum ISP1760 temperature will be approximately 40 °C (determined by the ambient temperature) so the ISP1760 maximum suspend current will be below 300 µA. An alternative solution to achieve a very low suspend current is to completely switch off the V
CC(5V0)
pins of the processor. This is possible because the ISP1760 can be used in the hybrid mode, which allows only the V
The time from wake-up to suspend will be approximately 100 ms when the ISP1760 power is always on.
It is necessary to wait for the CLK_RDY interrupt assertion before programming the ISP1760 because internal clocks are stopped during deep-sleep suspend and restarted after the first wake-up event. The occurrence of the CLK_RDY interrupt means that the internal clocks are running and the normal functionality is achieved.

powered on to avoid loading of the system bus.
CC(I/O)
It is estimated that the CLK_RDY interrupt will be generated less than 100 µs after the wake-up event, if the power to the ISP1760 was on during suspend.
If the ISP1760 is used in the hybrid mode and V
CC(5V0)
is off during suspend, a 2 ms reset pulse is required when the power is switched back to on, before starting to program the resume state. This will ensure that the internal clocks are running and all logics reach a stable initial state.

7.7 Overcurrent detection

The ISP1760 can implement a digital or analog overcurrent detection scheme. Bit 15 of the HW Mode Control register can be programmed to select the analog or digital overcurrent detection. An analog overcurrent detection circuit is integrated on-chip. The main features of this circuit are self reporting, automatic resetting, low-trip time and low cost. This circuit offers an easy solution at no extra hardware cost on the board. The port power will be automatically disabled by the ISP1760 on an overcurrent event occurrence, by deasserting the PSWn_N signal without any software intervention.
When using the integrated analog overcurrent detection, the range of the overcurrent detection voltage for the ISP1760 is 45 mV to 100 mV. Calculation of the external components should be based on the 45 mV value, with the actual overcurrent detection threshold usually positioned in the middle of the interval.
Foran overcurrentlimit of 500 mA per port, a PMOS with R is required. If a PMOS with a lower R
is used, analog overcurrent detection can be

Fig 5. Adjusting analog overcurrent detection limit (optional).
The digital overcurrent scheme requires using an external power switch with integrated overcurrent detection, such as: LM3526, MIC2526 (2 ports) or LM3544 (4 ports). These devices are controlled by PSWn_N signals corresponding to each port. In the case of overcurrent occurrence, these devices will assert OCn_N signals. On OCn_N assertion, the ISP1760 cuts off the port power by deasserting PSWn_N. The external integrated power switch will also automatically cut-off the port power in the case of an overcurrent event, by implementing thermal shutdown. An internal delay filter of 1 ms to 3 ms will prevent false overcurrent reporting because of in-rush currents when plugging a USB device.

dips at t2–t3 and t4–t5. If the dip at t4–t5 is too short (that is, < 11 µs), the internal POR pulse will not react and will remain LOW. The internal POR starts with a 1 at t0. At t1, the detector will see the passing of the trip level and a delay element will add another t before it drops to 0.
The internal POR pulse will be generated whenever V than 11 µs.

8.2.4 FRINDEX register (R/W: 002Ch)
The Frame Index (FRINDEX) register is used by the Host Controller to index into the periodic frame list. The register updates every 125 µs (once each microframe). Bits n to 3 are used to select a particular entry in the Periodic Frame List during periodic schedule execution. The number of bits used for the index depends on the size of the frame list as set by the system software in the FLS (Frame List Size) field of the USBCMD register. This register must be written as a DoubleWord. A Word-onlywrite (16-bit mode) produces undefined results. This register cannot be written unless the Host Controller is in the halted state as indicated by the HCH (HCHalted) bit. A write to this register while the RS (Run/Stop) bit is set produces undefined results. Writes to this register also affectthe SOF value. The bit allocation is given in Table 18.

8.2.5 CTRLDSSEGMENT register (R/W: 0030h)
The Control Data Structure Segment (CTRLDSSEGMENT) register corresponds to the most significant address bits (63 to 32) for all EHCI data structures. If the 64AC (64-bit Addressing Capability) field in HCCPARAMS is cleared, then this register is not used and software cannot write to it (reading from this register returns zero).
If the 64AC(64-bit Addressing Capability) field in HCCPARAMS is set, this register is used with link pointers to construct 64-bit addresses to EHCI control data structures. This register is concatenated with the link pointer from either the PERIODICLISTBASE, ASYNCLISTADDR, or any control data structure link field to construct a 64-bit address.
This register allows the host software to locate all control data structures within the same 4 gigabytes memory segment.

8.2.7 PORTSC1 register (R/W: 0064h)
The Port Status and Control (PORTSC) register (bit allocation: Table 22) is in the power well. It is reset by hardware only when the auxiliary power is initially applied or in response to a Host Controller reset. The initial conditions of a port are:
No peripheral connected
Port disabled.
If the port has power control, software cannot change the state of the port until it sets the port power bits. Software must not attempt to change the state of the port until the power is stable on the port (maximum delay is 20 ms from the transition).

The standard EHCI data structures as described in
Specification for Universal Serial Bus Rev. 1.0
are optimized for the bus master operation
that is managed by the hardware state machine. The PTD structures of the ISP1760 are translations of the EHCI data structures that are
optimized for the ISP1760, while keeping the architecture of the EHCI data structures the same. This is because the ISP1760 is a slave Host Controller and has no bus master capability.
EHCI manages schedules in two lists: periodic and asynchronous. The data structures are designed to provide the maximum flexibility required by USB, minimize memory traffic, and hardware and software complexity. The ISP1760 controller executes transactions for devices by using a simple shared-memory schedule. This schedule consists of data structures organized into three lists.
qISO — Isochronous transfer qINTL — Interrupt transfer qATL — Asynchronous transfer; for the control and bulk transfers.
The system software maintains two lists for the Host Controller: periodic and asynchronous. The root of the periodic schedule—the PERIODICLISTBASE register—is the physical memory base address of the periodic frame list. The periodic frame list is an array memory pointer. The objects referenced from the frame list must be valid schedule data structures. The asynchronous list base is also a common list of queue heads (endpoints) that are served in a schedule. These endpoint data structures are further linked to the EHCI transfer descriptor that is the valid schedule (queue PTD).
The Periodic Schedule Enable (ISO_BUF_FULL and INT_BUF_FULL) or Asynchronous Schedule Enable (ATL_BUF_FULL) bits can enable traversal to these lists. Enabling a list indicates the presence of valid schedule in the list. The system software starts at these points, schedules the first transfer inside the shared memory of the ISP1760, and sets up the ATL, INTL or ITL bit corresponding to the type of transfer scheduled in the shared memory.
The ISP1760 has a maximum of 32 ISO, 32 INTL and 32 ATL PTDs. These PTDs are used as channels to transfer data from the shared memory to the USB bus. These channels are allocated and deallocated on receiving the transferfrom the core USB driver.

Page 56
Philips Semiconductors
Multiple transfers are scheduled to the shared memory for various endpoints bytraversing the next link pointer provided by the EHCI data structure, until it reaches the terminate bit in a microframe. If a schedule is enabled, the Host Controller starts executing from the ISO schedule, before it goes to the INTL schedule, and then to the ATL schedule.
The EHCI periodic and asynchronous lists are traversed by the software according to the EHCI traversal rule, and executed only from the asynchronous schedule after it encounters the end of the periodic schedule. The Host Controller traverses the ISO, INTL and ATL schedules. It fetches the element and begins traversing the graph of linked schedule data structures.
The last bit identifies the end of the schedule for each type of transfer, indicating the rest of the channels are empty. Once a transition is completed, the Host Controller executes from the next transfer descriptor in the schedule until the end of the microframe.
The completion of a transfer is indicated to the software by the interrupt that can be grouped over the various PTDs by using the AND or OR registers that are available for each schedule type (ISO, INTL and ATL). These registers are simple logic registers to decide the group and individual PTDs that can interrupt the CPU for a schedule, when the logical conditions of the done bit is true in the shared memory that completes the interrupt.
ISP1760
Embedded Hi-Speed USB host controller
Interrupts are of four types and the latency can be programmed in multiples of µSOF (125 µs).
ISO interrupt
INTL interrupt
ATL Interrupt
SOF—start of frame interrupt for the data transfer.
A static PTD that schedules inside the ISP1760 shared memory allows using the NextPTD mechanism that will enable the Host Controller driver to schedule the multiple PTDs that are of single endpoint and reduce the interrupt to the CPU.
The NextPTD traversal rules defined by the ISP1760 hardware are:
1. Start the ATL header traversal.
2. If the current PTD is active and not done, perform the transaction.
3. Follow the next link pointer.
4. If PTD is not active and done, jump to the next PTD.
5. If the next link pointer is NULL, it means the end of the traversal.

All bits can be set to one for every transfer. It specifies which µSOF the complete split needs to be sent. Valid only for IN. Start split (SS) and complete split (CS) active bits—µSA = 0000 0001, µS CS = 0000 0100—will cause SS to execute in µFrame0 and CS in µFrame2.
Bit 0 — Transaction Error (IN and OUT) Bit 1 — Babble (IN token only) Bit 2 — underrun (OUT token only).
Specifies which µSOF the start split needs to be placed. For OUT token: When the frame number of bits DW1(7-3) matches the
frame number of the USB bus, these bits are checked for one before they are sent for the µSOF.
For IN token: Only µSOF0, µSOF1, µSOF2 or µSOF3 can be set to 1. Nothing can be set for µSOF4 and above.

frame number of the USB bus, these bits are checked for one before they are sent for the µSOF.
For IN token: Only µSOF0, µSOF1, µSOF2 or µSOF3 can be set to 1. Nothing can be set for µSOF4 and above.

Remark: The idle operating current, that is, when the ISP1760 is in operational
mode—initialized and without any devices connected, is 70 mA. The additional current consumption on ICC is below 1 mA per port in the case of full-speed and low-speed devices.
Remark: Deep-sleep suspend mode ensures the lowest power consumption when VCCis always supplied to the ISP1760. In this case, the suspend current is typically about 100 µA at room temperature. The suspend current may increase if the ambient temperature increases. For details, see Section 7.6.
Remark: In hybrid mode, when VCC is disconnected I
will be generally below

16. Soldering

16.1 Introduction to soldering surface mount packages

This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our (document order number 9398 652 90011).
There is no soldering method that is ideal for all surface mount IC packages. Wave soldering can still be used for certain surface mount ICs, but it is not suitable for fine pitch SMDs. In these situations reflow soldering is recommended.
16.2 Reflow soldering
Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing.
Several methods exist for reflowing; for example, convection or convection/infrared heating in a conveyor type oven. Throughput times (preheating, soldering and cooling) vary between 100 and 200 seconds depending on heating method.
ISP1760
Embedded Hi-Speed USB host controller
Data Handbook IC26; Integrated Circuit Packages
Typical reflow peak temperatures range from 215 to 270 °C depending on solder paste material. The top-surface temperature of the packages should preferably be kept:
below 225 °C (SnPb process) or below 245 °C (Pb-free process)
for all BGA, HTSSON..T and SSOP..T packagesfor packages with a thickness 2.5 mmfor packages with a thickness < 2.5 mm and a volume 350 mm3 so called
thick/large packages.
below 240 °C (SnPb process) or below 260 °C (Pb-free process) for packages with a
thickness < 2.5 mm and a volume < 350 mm3 so called small/thin packages.
Moisture sensitivity precautions, as indicated on packing, must be respected at all times.

16.3 Wave soldering

Conventional single wave soldering is not recommended for surface mount devices (SMDs) or printed-circuit boards with a high component density, as solder bridging and non-wetting can present major problems.
To overcome these problems the double-wave soldering method was specifically developed.
If wave soldering is used the following conditions must be observed for optimal results:
Use a double-wave soldering method comprising a turbulent wave with high upward
pressure followed by a smooth laminar wave.
For packages with leads on two sides and a pitch (e):
larger than or equal to 1.27 mm, the footprint longitudinal axis is preferred to be
parallel to the transport direction of the printed-circuit board;

Philips Semiconductors
smaller than 1.27 mm, the footprint longitudinal axis must be parallel to the
The footprint must incorporate solder thieves at the downstream end.
For packages with leads on four sides, the footprint must be placed at a 45° angle to
the transport direction of the printed-circuit board. The footprint must incorporate solder thieves downstream and at the side corners.
During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured.
Typical dwell time of the leads in the wave ranges from 3 to 4 seconds at 250 °C or 265 °C, depending on solder material applied, SnPb or Pb-free respectively.
A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications.

16.4 Manual soldering

Fix the component by first soldering two diagonally-opposite end leads. Use a low voltage (24 V or less) soldering iron applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C.

transport direction of the printed-circuit board.
When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C.

[4] These packages are not suitable for wave soldering. On versions with the heatsink on the bottom side, the
solder cannot penetrate between the printed-circuit board and the heatsink. On versions with the heatsink on the top side, the solder might be deposited on the heatsink surface.
[5] If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave
direction. The package footprint must incorporate solder thieves downstream and at the side corners.
[6] Wave soldering is suitable for LQFP, QFP and TQFP packages with a pitch (e) larger than 0.8 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65mm.
[7] Wave soldering is suitable for SSOP, TSSOP, VSO and VSOP packages with a pitch (e) equal to or larger
than 0.65 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
[8] Image sensor packages in principle should not be soldered. They are mounted in sockets or delivered
pre-mounted on flex foil. However, the image sensor package can be mounted by the client on a flex foil by using a hot bar soldering process. The appropriate soldering profile can be provided on request.
[9] Hot bar soldering or manual soldering is suitable for PMFP packages.
