Cypress’s EZ-USB® FX2LP (CY7C68013A/14A) is a low power version of the EZ-USB FX2(CY7C68013), which is a highly integrated, low power USB 2.0 microcontroller. By integrating the USB 2.0 transceiver, serial interface engine (SIE), enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip,

Cypress has created a cost effective solution that provides superior time-to-market advantages with low power to enable bus powered applications.

The ingenious architecture of FX2LP results in data transfer rates of over 53 Mbytes per second, the maximum allowable USB 2.0 bandwidth, while still using a low cost 8051 microcontroller in a package as small as a 56 VFBGA (5 mm x 5 mm). Because it incorporates the USB 2.0 transceiver, the FX2LP is more economical, providing a smaller footprint solution

Document #: 38-08032 Rev. *V Page 2 of 66

than USB 2.0 SIE or external transceiver implementations. With EZ-USB FX2LP, the Cypress Smart SIE handles most of the USB 1.1 and 2.0 protocol in hardware, freeing the embedded microcontroller for application specific functions and decreasing development time to ensure USB compatibility.

The General Programmable Interface (GPIF) and Master/Slave Endpoint FIFO (8-bit or 16-bit data bus) provides an easy and glueless interface to popular interfaces such as

A TA, UTOPIA,

EPP, PCMCIA, and most DSP/processors. The FX2LP draws less current than the FX2 (CY7C68013), has

double the on-chip code/data RAM, and is fit, form and function compatible with the 56, 100, and 128 pin FX2.

Five packages are defined for the family: 56 VFBGA, 56 SSOP, 56 QFN, 100 TQFP, and 128 TQFP.

2. Functional Overview

2.1 USB Signaling Speed

FX2LP operates at two of the three rates defined in the USB Specification Revision 2.0, dated April 27, 2000:

■ Full speed, with a signaling bit rate of 12 Mbps

■ High speed, with a signaling bit rate of 480 Mbps

FX2LP does not support the low speed signaling mode of

1.5 Mbps.

2.2 8051 Microprocessor

The 8051 microprocessor embedded in the FX2LP family has 256 bytes of register RAM, an expanded interrupt system, three timer/counters, and two USARTs.

2.2.1 8051 Clock Frequency

FX2LP has an on-chip oscillator circuit that uses an external 24 MHz (±100 ppm) crystal with the following characteristics:

■ Parallel resonant

■ Fundamental mode

■ 500 W drive level

■ 12 pF (5% tolerance) load capacitors

An on-chip PLL multiplies the 24 MHz oscillator up to 480 MHz, as required by the transceiver/PHY and internal counters divide it down for use as the 8051 clock. The default 8051 clock frequency is 12 MHz. The clock frequency of the 8051 can be changed by the 8051 through the CPUCS register, dynamically.

Figure 2-1. Crystal Configuration

The CLKOUT pin, which can be three-stated and inverted using internal control bits, outputs the 50% duty cycle 8051 clock, at the selected 8051 clock frequency: 48 MHz, 24 MHz, or 12 MHz.

2.2.2 USARTs

FX2LP contains two standard 8051 USART s, addressed through Special Function Register (SFR) bits. The USART interface pins are available on separate I/O pins, and are not multiplexed with port pins.

UART0 and UART1 can operate using an internal clock at 230 KBaud with no more than 1% baud rate error. 230 KBaud operation is achieved by an internally derived clock source that generates overflow pulses at the appropriate time. The internal clock adjusts for the 8051 clock rate (48 MHz, 24 MHz, and 12 MHz) such that it always presents the correct frequency for 230 KBaud operation.

[1]

2.2.3 Special Function Registers

Certain 8051 SFR addresses are populated to provide fast access to critical FX2LP functions. These SFR additions are shown in Table 1 on page 5. Bold type indicates non standard, enhanced 8051 registers. The two SFR rows that end with “0” and “8” contain bit addressable registers. The four I/O ports A to D use the SFR addresses used in the standard 8051 for ports 0 to 3, which are not implemented in FX2LP . Because of the faster and more efficient SFR addressing, the FX2LP I/O ports are not addressable in external RAM space (using the MOVX instruction).

2.3 I2C Bus

FX2LP supports the I2C bus as a master only at 100/400 KHz. SCL and SDA pins have open-drain outputs and hysteresis inputs. These signals must be pulled up to 3.3V, even if no I

device is connected.

2.4 Buses

All packages, 8-bit or 16-bit “FIFO” bidirectional data bus, multiplexed on I/O ports B and D. 128-pin package: adds 16-bit output-only 8051 address bus, 8-bit bidirectional data bus.

2.5 USB Boot Methods

During the power up sequence, internal logic checks the I2C port for the connection of an EEPROM whose first byte is either 0xC0 or 0xC2. If found, it uses the VID/PID/DID values in the EEPROM in place of the internally stored values (0xC0), or it boot-loads the EEPROM contents into internal RAM (0xC2). If no EEPROM is detected, FX2LP enumerates using internally stored descriptors. The default ID values for FX2LP are VID/PID/DID (0x04B4, 0x8613, 0xAxxx where xxx = Chip revision).

Table 2. Default ID Values for FX2LP

Default VID/PID/DID

Vendor ID 0x04B4 Cypress Semiconductor Product ID 0x8613 EZ-USB FX2LP Device release 0xAnnn Depends on chip revision

(nnn = chip revision where first silicon = 001)

[2]

2.6 ReNumeration

Because the FX2LP’s configuration is soft, one chip can take on the identities of multiple distinct USB devices.

When first plugged into USB, the FX2LP enumerates automatically and downloads firmware and USB descriptor tables over the USB cable. Next, the FX2LP enumerates again, this time as a device defined by the downloaded information. This patented two step process called ReNumeration happens instantly when the device is plugged in, without a hint that the initial download step has occurred.

Two control bits in the USBCS (USB Control and S tatus) register, control the ReNumeration process: DISCON and RENUM. To simulate a USB disconnect, the firmware sets DISCON to 1. To reconnect, the firmware clears DISCON to 0.

Before reconnecting, the firmware sets or clears the RENUM bit to indicate whether the firmware or the Default USB Device handles device requests over endpoint zero: if RENUM = 0, the Default USB Device handles device requests; if RENUM = 1, the firmware services the requests.

2.7 Bus-Powered Applications

The FX2LP fully supports bus powered designs by enumerating with less than 100 mA as required by the USB 2.0 specification.

2.8 Interrupt System

2.8.1 INT2 Interrupt Request and Enable Registers

FX2LP implements an autovector feature for INT2 and INT4. There are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF) vectors. See EZ-USB Technical Reference Manual (TRM) for more details.

2.8.2 USB Interrupt Autovectors

The main USB interrupt is shared by 27 interrupt sources. To save the code and processing time that is required to identify the individual USB interrupt source, the FX2LP provides a second level of interrupt vectoring, called Autovectoring. When a USB interrupt is asserted, the FX2LP pushes the program counter to its stack, and then jumps to the address 0x0043 where it expects to find a “jump” instruction to the USB Interrupt service routine.

Document #: 38-08032 Rev. *V Page 5 of 66

CY7C68013A, CY7C68014A CY7C68015A, CY7C68016A

The FX2LP jump instruction is encoded as follows:

If Autovectoring is enabled (AV2EN = 1 in the INTSET-UP register), the FX2LP substitutes its INT2VEC byte. Therefore, if the high byte (“page”) of a jump table address is preloaded at the location 0x0044, the automatically inserted INT2VEC byte at 0x0045 directs the jump to the correct address out of the 27 addresses within the page.

2.8.3 FIFO/GPIF Interrupt (INT4)

Just as the USB Interrupt is shared among 27 individual USB interrupt sources, the FIFO/GPIF interrupt is shared among 14 individual FIFO/GPIF sources. The FIFO/GPIF Interrupt, similar to the USB Interrupt, can employ autovectoring. Table 4 on page 7 shows the priority and INT4VEC values for the 14 FIFO/GPIF interrupt sources.

If Autovectoring is enabled (AV4EN = 1 in the INTSET-UP register), the FX 2LP substitutes its INT4VEC byte. Therefore, if the high byte (“page”) of a jump-table address is preloaded at location 0x0054, the automatically inserted INT4VEC byte at 0x0055 directs the jump to the correct address out of the 14 addresses within the page. When the ISR occurs, the FX2LP pushes the program counter to its stack then jumps to address 0x0053, where it expects to find a “jump” instruction to the ISR Interrupt service routine.

2.9 Reset and Wakeup

2.9.1 Reset Pin

The input pin, RESET#, resets the FX2LP when asserted. This pin has hysteresis and is active LOW. When a crystal is used with the CY7C680xxA the reset period must enable stabilization of the crystal and the PLL. This reset period must be approximately

5 ms after VCC reaches 3.0V . If the cryst al input pin is driven by a clock signal the internal PLL stabilizes in 200 s after VCC has reached 3.0V.

Figure 2-2 on page 8 shows a power on reset condition and a

reset applied during operation. A power on reset is defined as the time reset that is asserted while power is being applied to the circuit. A powered reset is when the FX2LP powered on and operating and the RESET# pin is asserted.

Cypress provides an application note which describes and recommends power on reset implementation. For more information about reset implementation for the FX2 family of products visit http://www.cypress.com.

2.9.2 Wakeup Pins

The 8051 puts itself and the rest of the chip into a power down mode by setting PCON.0 = 1. This stops the oscillator and PLL. When WAKEUP is asserted by external logic the oscillator restarts after the PLL stabilizes, and the 8051 receives a wakeup interrupt. This applies whether or not FX2LP is connected to the USB.

The FX2LP exits the power down (USB suspend) state using one of the following methods:

■ USB bus activity (if D+/D– lines are left floating, noise on these

lines may indicate activity to the FX2LP and initiate a wakeup)

■ External logic asserts the WAKEUP pin

■ External logic asserts the PA3/WU2 pin

The second wakeup pin, WU2, can also be configured as a general purpose I/O pin. This enables a simple external R-C network to be used as a periodic wakeup source. WAKEUP is by default active LOW.

2.10 Program/Data RAM

2.10.1 Size

The FX2LP has 16 KBytes of internal program/d ata RAM, where PSEN#/RD# signals are internally ORed to enable the 8051 to access it as both program and data memory. No USB control registers appear in this space.

Two memory maps are shown in the following diagrams:

Figure 2-3 on page 9 shows the Internal Code Memory, EA = 0 Figure 2-4 on page 10 shows the External Code Memory, EA = 1.

2.10.2 Internal Code Memory, EA = 0

This mode implements the internal 16 KByte block of RAM (starting at 0) as combined code and data memory. When external RAM or ROM is added, the external read and write strobes are suppressed for memory spaces that exist inside the chip. This enables the user to connect a 64 KByte memory without requiring address decodes to keep clear of internal memory spaces.

Only the internal 16 KBytes and scratch pad 0.5 KBytes RAM spaces have the following access:

■ USB download

■ USB upload

■ Setup data pointer

■ I

C interface boot load.

2.10.3 External Code Memory, EA = 1

The bottom 16 KBytes of program memory is external and therefore the bottom 16 KBytes of internal RAM is accessible only as a data memory.

Figure 2-5. Endpoint Configuration

2.12.3 Setup Data Buffer

A separate 8 byte buffer at 0xE6B8-0xE6BF holds the setup data from a CONTROL transfer.

2.12.4 Endpoint Configurations (High Speed Mode)

Endpoints 0 and 1 are the same for every configuration. Endpoint 0 is the only CONTROL endpoint, and endpoint 1 can be either BULK or INTERRUPT.

The endpoint buffers can be configured in any 1 of the 12 configurations shown in the vertical columns. When operating in the full speed BULK mode only the first 64 bytes of each buffer are used. For example, in high speed, the max packet size is 512 bytes but in full speed it is 64 bytes. Even though a buffer is configured to a 512 byte buffer, in full speed only the first 64 bytes are used. The unused endpoint buffer space is not available for other operations. An example endpoint configuration is the EP2–1024 double buffered; EP6–512 quad buffered (column 8).

2.13 External FIFO Interface

2.13.1 Architecture

The FX2LP slave FIFO architecture has eight 512 byte blocks in the endpoint RAM that directly serve as FIFO memories and are controlled by FIFO control signals (such as IFCLK, SLCS#, SLRD, SLWR, SLOE, PKTEND, and flags).

In operation, some of the eight RAM blocks fill or empty from the SIE, while the others are connected to the I/O transfer logic. The transfer logic takes two forms, the GPIF for internally generated control signals and the slave FIFO interface for externally controlled transfers.

2.13.2 Master/Slave Control Signals

The FX2LP endpoint FIFOS are implemented as eight physically distinct 256x16 RAM blocks. The 8051/SIE can switch any of the RAM blocks between two domains, the USB (SIE) domain and the 8051-I/O Unit domain. This switching is done virtually instantaneously, giving essentially zero transfer time between “USB FIFOS” and “Slave FIFOS.” Because they are physically the same memory no bytes are actually transferred between buffers.

At any time, some RAM blocks are filling/emptying with USB data under SIE control, while other RAM blocks are available to the 8051, the I/O control unit or both. The RAM blocks operate as single port in the USB domain, and dual port in the 8051-I/O

domain. The blocks can be configured as single, double, triple, or quad buffered as previously shown.

The I/O control unit implements either an internal master (M for master) or external master (S for Slave) interface.

In Master (M) mode, the GPIF internally controls FIFOADR[1..0] to select a FIFO. The RDY pins (two in the 56-pin package, six in the 100-pin and 128-pin packages) can be used as flag inputs from an external FIFO or other lo gic if desired. The GPIF can be run from either an internally derived clock or externally supplied clock (IFCLK), at a rate that transfers data up to 96 Megabytes/s (48 MHz IFCLK with 16-bit interface).

In Slave (S) mode, the FX2LP accepts either an internally derived clock or externally supplied clock (IFCLK, max frequency 48 MHz) and SLCS#, SLRD, SLWR, SLOE, PKTEND signals from external logic. When using an external IFCLK, the external clock must be present before switching to the external clock with the IFCLKSRC bit. Each endpoint can individually be selected for byte or word operation by an internal configuration bit and a Slave FIFO Output Enable signal SLOE enables data of the selected width. External logic must ensure that the output enable signal is inactive when writing data to a slave FIFO. The slave interface can also operate asynchronously, where the SLRD and SLWR signals act directly as strobes, rather than a clock qualifier as in synchronous mode. The signals SLRD, SLWR, SLOE and PKTEND are gated by the signal SLCS#.

2.13.3 GPIF and FIFO Clock Rates

Notes

7. T o use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation.

8. After the data is downloaded from the host, a “loader” can execute from internal RAM to transfer downloaded data to external memory.

An 8051 register bit selects one of two frequencies for the internally supplied interface clock: 30 MHz and 48 MHz. Alternatively, an externally supplied clock of 5 MHz–48 MHz feeding the IFCLK pin can be used as the interface clock. IFCLK can be configured to function as an output clock when the GPIF and FIFOs are internally clocked. An output enable bit in the IFCONFIG register turns this clock output off, if desire d. Another bit within the IFCONFIG register inverts the IFCLK signal whether internally or externally sourced.

2.14 GPIF

The GPIF is a flexible 8-bit or 16-bit parallel interface driven by a user programmable finite state machine. It enables the CY7C68013A/15A to perform local bus mastering and can implement a wide variety of protocols such as ATA interface, printer parallel port, and Utopia.

The GPIF has six programmable control outputs (CTL), nine address outputs (GPIFADRx), and six general-purpose ready inputs (RDY). The data bus width can be 8 or 16 bits. Each GPIF vector defines the state of the control outputs, and determines what state a ready input (or multiple inputs) must be before proceeding. The GPIF vector can be programmed to advance a FIFO to the next data value, advance an address, etc. A sequence of the GPIF vectors make up a single waveform that is executed to perform the desired data move between the FX2LP and the external device.

2.14.1 Six Control OUT Signals

The 100-pin and 128-pin packages bring out all six Control Output pins (CTL0-CTL5). The 8051 programs the GPIF unit to define the CTL waveforms. The 56-pin package brings out three of these signals, CTL0–CTL2. CTLx waveform edges can be programmed to make transitions as fast as once per clock (20.8 ns using a 48 MHz clock).

2.14.2 Six Ready IN Signals

The 100-pin and 128-pin packages bring out all six Ready inputs (RDY0–RDY5). The 8051 programs the GPIF unit to test the RDY pins for GPIF branching. The 56-pin package brings out two of these signals, RDY0–1.

2.14.3 Nine GPIF Address OUT Signals

Nine GPIF address lines are available in the 100-pin and 128-pin packages, GPIFADR[8..0]. The GPIF address lines enable indexing through up to a 512 byte block of RAM. If more address lines are needed I/O port pins are used.

2.14.4 Long Transfer Mode

In the master mode, the 8051 appropriately sets GPIF transaction count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1, or GPIFTCB0) for unattended transfers of up to 2 The GPIF automatically throttles data flow to prevent under or overflow until the full number of requested transactions complete. The GPIF decrements the value in these registers to represent the current status of the transaction.

transactions.

2.15 ECC Generation

The EZ-USB can calculate ECCs (Error Correcting Codes) on data that passes across its GPIF or Slave FIFO interfaces. There are two ECC configurations: Two ECCs, each calculated over 256 bytes (SmartMedia Standard); and one ECC calculated over 512 bytes.

The ECC can correct any one-bit error or detect any two-bit error.

2.15.1 ECC Implementation

The two ECC configurations are selected by the ECCM bit:

ECCM = 0

Two 3 byte ECCs, each calculated over a 256 byte block of data. This configuration conforms to the SmartMedia Standard.

Write any value to ECCRESET, then pass data across the GPIF or Slave FIFO interface. The ECC for the first 256 bytes of data is calculated and stored in ECC1. The ECC for the next 256 bytes is stored in ECC2. After the second ECC is calculated, the values in the ECCx registers do not change until ECCRESET is written again, even if more data is subsequently passed across the interface.

ECCM = 1

One 3 byte ECC calculated over a 512 byte block of data. Write any value to ECCRESET then pass data across the GPIF

or Slave FIFO interface. The ECC for the first 512 bytes of data is calculated and stored in ECC1; ECC2 is unused. After the ECC is calculated, the values in ECC1 do not change even if more data is subsequently passed across the interface, till ECCRESET is written again.

[7]

2.16 USB Uploads and Downloads

The core has the ability to directly edit the da ta contents of the internal 16 KByte RAM and of the internal 512 byte scratch pad RAM via a vendor specific command. This capability is normally used when soft downloading user code and is available only to and from internal RAM, only when the 8051 is held in reset. The available RAM spaces are 16 KBytes from 0x0000–0x3FFF (code/data) and 512 bytes from 0xE000–0xE1FF (scratch pad data RAM).

[8]

2.17 Autopointer Access

FX2LP provides two identical autopointers. They are similar to the internal 8051 data pointers but with an additional feature: they can optionally increment after every memory access. This capability is available to and from both internal and external RAM. The autopointers are available in external FX2LP registers under control of a mode bit (AUTOPTRSET-UP.0). Using the external FX2LP autopointer access (at 0xE67B – 0xE67C) enables the autopointer to access all internal and external RAM to the part.

Also, the autopointers can point to any FX2LP register or endpoint buffer space. When autopointer access to external memory is enabled, location 0xE67B and 0xE67C in XDAT A and code space cannot be used.

2.19 Compatible with Previous Generation

EZ-USB FX2

The EZ-USB FX2LP is form, fit and with minor exceptions functionally compatible with its predecessor, the EZ-USB FX2. This makes for an easy transition for designers wanting to upgrade their systems from the FX2 to the FX2LP. The pinout and package selection are ide nt i cal an d a vast majo ri ty of firmware previously developed for the FX2 functions in the FX2LP.

2.20 CY7C68013A/14A and CY7C68015A/16A Differences

CY7C68013A is identical to CY7C68014A in form, fit, and functionality. CY7C68015A is identical to CY7C68016A in form, fit, and functionality. CY7C68014A and CY7C68016A have a lower suspend current than CY7C68013A and CY7C68015A respectively and are ideal for power sensitive battery applications.

CY7C68015A and CY7C68016A are available in 56-pin QFN package only. Two additional GPIO signals are available on the CY7C68015A and CY7C68016A to provide more flexibility when neither IFCLK or CLKOUT are needed in the 56-pin package.

USB developers wanting to convert their FX2 56-pin application to a bus-powered system directly benefit from these additional signals. The two GPIOs give developers the signals they need for the power control circuitry of their bus-powered application without pushing them to a high pincount version of FX2LP.

The CY7C68015A is only available in the 56-pin QFN package

3. Pin Assignments

Figure 3-1 on page 16 identifies all signals for the five package

types. The following pages illustrate the individual pin diagrams, plus a combination diagram showing which of the full set of signals are available in the 128-pin, 100-pin, and 56-pin packages.

The signals on the left edge of the 56-pin package in Figure 3-1

on page 16 are common to all versions in the FX2LP family with

the noted differences between the CY7C68013A/14A and the CY7C68015A/16A.

Three modes are available in all package versi o n s: Port , GPIF master, and Slave FIFO. These modes define the signals on the right edge of the diagram. The 8051 selects the interface mode using the IFCONFIG[1:0] register bits. Port mode is the power on default configuration.

The 100-pin package adds functionality to the 56-pin package by adding these pins:

■ PORTC or alternate GPIFADR[7:0] address signals

■ PORTE or alternate GPIFADR[8] address signal and seven

additional 8051 signals

■ Three GPIF Control signals

■ Four GPIF Ready signals

■ Nine 8051 signals (two USART s, three timer inputs, INT4,and

INT5#)

■ BKPT, RD#, WR#.

The 128-pin package adds the 8051 address and data buses plus control signals. Note that two of the required signals, RD# and WR#, are present in the 100-pin version.

In the 100-pin and 128-pin versions, an 8051 control bit can be set to pulse the RD# and WR# pins when the 8051 reads from/writes to PORTC. This feature is enabled by setting PORTCSTB bit in CPUCS register.

Section 9.5 displays the timing diagram of the read and write

strobing function on accessing PORTC.

The RD# and WR# are present in the 100-pin version and the 128-pin package. In these 100-pin and 128-pin versions, an 8051 control bit can be set to pulse the RD# and WR# pins when the 8051 reads from or writes to PORTC. This feature is enabled by setting PORTCSTB bit in CPUCS register.

The RD# and WR# strobes are asserted for two CLKOUT cycles when PORTC is accessed.

The WR# strobe is asserted two clock cycles after PORTC is updated and is active for two clock cycles after that, as shown in

Figure 9-4.

As for read, the value of PORTC three clock cycles before the assertion of RD# is the value that the 8051 reads in. The RD# is pulsed for 2 clock cycles after 3 clock cycles from the point when the 8051 has performed a read function on PORTC.

Figure 9-4. WR# Strobe Function when PORTC is Accessed by 8051

The RD# signal prompts the external logic to prepare the next data byte. Nothing gets sampled internally on assertion of the RD# signal itself, it is just a prefetch type signal to get the next data byte prepared. So, using it with that in mind easily meets the setup time to the next read.

The purpose of this pulsing of RD# is to allow the external peripheral to know that the 8051 is done reading PORTC and the data was latched into PORTC three CLKOUT cycles before asserting the RD# signal. After the RD# is pulsed, the external logic can update the data on PORTC.

Following is the timing diagram of the read and write strobing function on accessing PORTC. Refer to Section 9.3 and Section

9.4 for details on propagation delay of RD# and WR# signals.

Although there are no specific timing requirements for the PKTEND assertion, there is a specific corner case condition that needs attention while using the PKTEND to commit a one byte or word packet. There is an additional timing requirement that needs to be met when the FIFO is configured to operate in auto mode and it is required to send two packets back to back: a full packet (full defined as the number of bytes in the FIFO meeting the level set in AUTOINLEN register) committed automatically followed by a short one byte or word packet committed manually using the PKTEND pin. In this scenario, the user must ensure to assert PKTEND at least one clock cycle after the rising edge that

Figure 9-12. Slave FIFO Synchronous Write Sequence and Timing Diagram

caused the last byte or word to be clocked into the previous auto committed packet. Figure 9-12 shows this scenario. X is the value the AUTOINLEN register is set to when the IN endpoint is configured to be in auto mode.

Figure 9-12 shows a scenario where two packets are committed.

The first packet gets committed automatically when the number of bytes in the FIFO reaches X (value set in AUTOINLEN register) and the second one byte/word short packet being committed manually using PKTEND.

Note that there is at least one IFCLK cycle timing between the assertion of PKTEND and clocking of the last byte of the previous packet (causing the packet to be committed automatically). Failing to adhere to this timing results in the FX2 failing to send the one byte or word short packet.

The same sequence of events are also shown for a burst write and are marked with the time indicators of T = 0 through 5.

Note For the burst mode, SLWR and SLCS are left asserted for the entire duration of writing all the required data values. In this burst write mode, after the SLWR is asserted, the data on the FIFO data bus is written to the FIFO on every rising edge of IFCLK. The FIFO pointer is updated on each rising edge of IFCLK. In Figure 9-20, after the four bytes are written to the FIFO, SLWR is deasserted. The short 4 byte packet can be committed to the host by asserting the PKTEND signal.

There is no specific timing requirement that should be met for asserting PKTEND signal with regards to asserting the SLWR signal. PKTEND can be asserted with the last data value or thereafter. The only requirement is that the setup time t the hold time t the number of data values committed includes the last value

must be met. In the scenario of Figure 9-20,

Although there are no specific timing requirement for the PKTEND assertion, there is a specific corner case condition that needs attention while using the PKTEND to commit a one byte/word packet. Additional timing requirements exists when the FIFO is configured to operate in auto mode and it is desired to send two packets: a full packet (full defined as the number of bytes in the FIFO meeting the level set in AUTOINLEN register) committed automatically followed by a short one byte or word packet committed manually using the PKTEND pin.

In this case, the external master must ensure to assert the PKTEND pin at least one clock cycle after the rising edge that caused the last byte or word that needs to be clocked into the previous auto committed packet (the packet with the number of bytes equal to what is set in the AUTOINLEN register). Refer to

Figure 9-12 on page 48 for further details on this timing.

The same sequence of events is also shown for a burst read marked with T = 0 through 5.

Note In burst read mode, during SLOE is assertion, the data bus is in a driven state and outputs the previous data. After SLRD is asserted, the data from the FIFO is driven on the data bus (SLOE must also be asserted) and then the FIFO pointer is incremented.

Figure 9-23. Slave FIFO Asynchronous Write Sequence and Timing Diagram

[20]

Figure 9-23 shows the timing relationship of the SLAVE FIFO

write in an asynchronous mode. The diag r am shows a single write followed by a burst write of 3 bytes and committing the 4 byte short packet using PKTEND.

■ At t = 0 the FIFO address is applied, insuring that it meets the

setup time of t (SLCS may be tied low in some applications).

■ At t = 1 SLWR is asserted. SLWR must meet the minimum

from the deasserting

XFLG

The same sequence of events are shown for a burst write and is indicated by the timing marks of T = 0 through 5.

Note In the burst write mode, after SL WR is deasserted, the data is written to the FIFO and then the FIFO pointer is incremented to the next byte in the FIFO. The FIFO pointer is post incremented.

In Figure 9-23 after the four bytes are written to the FIFO and SLWR is deasserted, the short 4 byte packet can be committed to the host using the PKTEND. The external device should be designed to not assert SLWR and the PKTEND signal at the same time. It should be designed to assert the PKTEND after SLWR is deasserted and met the minimum deasserted pulse width. The FIFOADDR lines have to held constant during the PKTEND assertion.

12. PCB Layout Recommendations

Note

25.Source for recommendations: EZ-USB FX2™PCB Design Recommendations, http://www.cypress.com and High Speed USB Platform Design Guidelines,

http://www.usb.org/developers/docs/hs_usb_pdg_r1_0.pdf.

Follow these recommendations to ensure reliable high performance operation:

■ Four layer impedance controlled boards are required to

[25]

maintain signal quality.

■ Specify impedance targets (ask your board vendor what they

can achieve).

■ T o control impedance, maintain trace widths and trace spacing.

■ Minimize stubs to minimize reflected signals.

■ Connections between the USB connector shell and signal

ground must be near the USB connector.

■ Bypass and flyback caps on VBus, near connector, are

recommended.

■ DPLUS and DMINUS trace lengths should be kept to within

2 mm of each other in length, with preferred length of 20 to 30 mm.

■ Maintain a solid ground plane under the DPLUS and DMINUS

traces. Do not allow the plane to split under these traces.

■ Do not place vias on the DPLUS or DMINUS trace routing.

■ Isolate the DPLUS and DMINUS traces from all other signal

traces by no less than 10 mm.

Figure 13-2. Plot of the Solder Mask (White Area)

Figure 13-3. X-ray Image of the Assembly

Electrical contact of the part to the Printed Circuit Board (PCB) is made by soldering the leads on the bottom surface of the package to the PCB. Hence, special attention is required to the heat transfer area below the package to provide a good thermal bond to the circuit board. Design a Copper (Cu) fill in the PCB as a thermal pad under the package. Heat is transferred from the FX2LP through the device’s metal paddle on the bottom side of the package. Heat from here is conducted to the PCB at the thermal pad. It is then conducted from the thermal pad to the PCB inner ground plane by a 5 × 5 array of via. A via is a plated through hole in the PCB with a finished diameter of 13 mil. The QFN’s metal die paddle must be soldered to the PCB’s thermal pad. Solder mask is placed on the board top side over each via to resist solder flow into the via. The mask on the top side also minimizes outgassing during the solder reflow process.

Figure 13-1. Cross-section of the Area Underneath the QFN Package

For further information on this package design refer to Application Notes for Surface Mount Assembly of Amkor's MicroLeadFrame (MLF) Packages. You can find this on Amkor's website http://www.amkor.com.

The application note provides detailed information about board mounting guidelines, soldering flow, rework process, etc.

Figure 13-1 shows a cross-sectional area underneath the

package. The cross section is of only one via. The solder paste template should be designed to allow at least 50% solder coverage. The thickness of the solder paste template should be 5 mil. Use the No Clean type 3 solder paste for mounting the part. Nitrogen purge is recommended during reflow.

Figure 13-2 is a plot of the solder mask pattern and Figure 13-3

displays an X-Ray image of the assembly (darker areas indicate solder).
