Preliminary
Summary
32015AS-AVR32-02/07
1. Part Description
The AT32AP7001 is a complete System-on-chip application processor with an AVR32 RISC
processor achieving 210 DMIPS running at 150 MHz. AVR32 is a high-performance 32-bit RISC
microprocessor core, designed for cost-sensitive embedded applications, with particular emphasis on low power consumption, high code density and high application performance.
AT32AP7001 implements a Memory Management Unit (MMU) and a flexible interrupt controller
supporting modern operating systems and real-time operating systems. The processor also
includes a rich set of DSP and SIMD instructions, specially designed for multimedia and telecom
applications.
AT32AP7001 incorporates SRAM memories on-chip for fast and secure access. For applications requiring additional memory, external 16-bit SRAM is accessible. Additionally, an SDRAM
controller provides off-chip volatile memory access as well as controllers for all industry standard
off-chip non-volatile memories, like Compact Flash, Multi Media Card (MMC), Secure Digital
(SD)-card, SmartCard, NAND Flash and Atmel DataFlash™.
The Direct Memory Access controller for all the serial peripherals enables data transfer between
memories without processor intervention. This reduces the processor overhead when transferring continuous and large data streams between modules in the MCU.
The Timer/Counters includes three identical 16-bit timer/counter channels. Each channel can be
independently programmed to perform a wide range of functions including frequency measurement, event counting, interval measurement, pulse generation, delay timing and pulse width
modulation.
AT32AP7001
A pixel co-processor provides color space conversions for images and video, in addition to a
wide variety of hardware filter support
Synchronous Serial Controllers provide easy access to serial communication protocols, audio
standards like AC'97, I2S, I2C© and various SPI modes. The modules support frame-based protocols, like VoIP SIP protocols.
The Java hardware acceleration implementation in AVR32 allows for a very high-speed Java
byte-code execution. AVR32 implements Java instructions in hardware, reusing the existing
RISC data path, which allows for a near-zero hardware overhead and cost with a very high
performance.
The Image Sensor Interface supports cameras with up to 12-bit data buses and connects
directly to the LCD interface through a separate bus.
PS2 connectivity is provided for standard input devices like mice and keyboards.
AT32AP7001 integrates a class 3 Nexus 2.0 On-Chip Debug (OCD) System, with non-intrusive
real-time trace, full-speed read/write memory access in addition to basic runtime control.
The C-compiler is closely linked to the architecture and is able to utilize code optimization features, both for size and speed.

5. Power Considerations
5.1 Power Supplies
The AT32AP7001 has several types of power supply pins:
•
VDDCORE pins: Power the core, memories, and peripherals. Voltage is 1.8V nominal.
• VDDIO pins: Power I/O lines. Voltage is 3.3V nominal.
• VDDPLL pin: Powers the PLL. Voltage is 1.8V nominal.
• VDDUSB pin: Powers the USB. Voltage is 1.8V nominal.
• VDDOSC pin: Powers the oscillators. Voltage is 1.8V nominal.
The ground pins GND are common to VDDCORE and VDDIO. The ground pin for VDDPLL is
GNDPLL, and the GND pin for VDDOSC is GNDOSC.
See ”Electrical Characteristics” on page 928 for power consumption on the various supply pins.
5.2 Power Supply Connections
Special considerations should be made when connecting the power and ground pins on a PCB.
Figure 5-1 shows how this should be done.

6. I/O Line Considerations
6.1 JTAG pins
The TMS, TDI and TCK pins have pull-up resistors. TDO is an output, driven at up to VDDIO,
and have no pull-up resistor. The TRST_N pin is used to initialize the embedded JTAG TAP
Controller when asserted at a low level. It is a schmitt input and integrates permanent pull-up
resistor to VDDIO, so that it can be left unconnected for normal operations.
6.2 WAKE_N pin
The WAKE_N pin is a schmitt trigger input integrating a permanent pull-up resistor to VDDIO.
6.3 RESET_N pin
The RESET_N pin is a schmitt input and integrates a permanent pull-up resistor to VDDIO. As
the product integrates a power-on reset cell, the RESET_N pin can be left unconnected in case
no reset from the system needs to be applied to the product.
6.4 EVTI_N pin
The EVTI_N pin is a schmitt input and integrates a non-programmable pull-up resistor to VDDIO.
AT32AP7001
6.5 TWI pins
6.6 PIO pins
When these pins are used for TWI, the pins are open-drain outputs with slew-rate limitation and
inputs with inputs with spike-filtering. When used as GPIO-pins or used for other peripherals, the
pins have the same characteristics as PIO pins.
All the I/O lines integrate a programmable pull-up resistor. Programming of this pull-up resistor is
performed independently for each I/O line through the PIO Controllers. After reset, I/O lines
default as inputs with pull-up resistors enabled, except when indicated otherwise in the column
“Reset State” of the PIO Controller multiplexing tables.

The system bus is implemented as an HSB bus matrix. All system bus addresses are fixed, and
they are never remapped in any way, not even in boot. Note that AT32AP7001 by default uses
segment translation, as described in the AVR32 Architecture Manual. The 32 bit physical
address space is mapped as follows:

0xFFF0_0000 1 MByte PBB
Accesses to unused areas returns an error result to the master requesting such an access.
The bus matrix has the several masters and slaves. Each master has its own bus and its own
decoder, thus allowing a different memory mapping per master. The master number in the table
below can be used to index the HMATRIX control registers. For example, MCFG2 is associated
with the HSB-HSB bridge.

8.2 Interrupt Request Signal Map
The various modules may output interrupt request signals. These signals are routed to the Interrupt Controller (INTC). The Interrupt Controller supports up to 64 groups of interrupt requests.
Each group can have up to 32 interrupt request signals. All interrupt signals in the same group
share the same autovector address and priority level. Refer to the documentation for the individual submodules for a description of the semantic of the different interrupt requests.

8.7 Peripheral Multiplexing on IO lines
The AT32AP7001 features five PIO controllers, PIOA to PIOE, that multiplex the I/O lines of the
peripheral set. Each PIO Controller controls up to thirty-two lines.
Each line can be assigned to one of two peripheral functions, A or B. The tables in the following
pages define how the I/O lines of the peripherals A and B are multiplexed on the PIO
Controllers.
Note that some output only peripheral functions might be duplicated within the tables.

8.7.5 IO Pins Without Multiplexing
Many of the external EBI pins are not controlled by the PIO modules, but directly driven by the
EBI. These pins have programmable pullup resistors. These resistors are controlled by Special
Function Register 4 (SFR4) in the HMATRIX. The pullup on the lines multiplexed with PIO is
controlled by the appropriate PIO control register.
This SFR can also control CompactFlash, SmartMedia or NandFlash Support, see the EBI chapter for details

9. Boot Sequence
This chapter summarizes the boot sequence of the AT32AP7001. The behaviour after power-up
is controlled by the Power Manager.
9.1 Starting of clocks
After power-up, the device will be held in a reset state by the Power-On Reset circuitry, until the
power has stabilized throughout the device. Once the power has stabilized, the device will use
the XIN0 pin as clock source. XIN0 can be connected either to an external clock, or a crystal.
The OSCEN_N pin is connected either to VDD or GND to inform the Power Manager on how the
XIN0 pin is connected. If XIN0 receives a signal from a crystal, dedicated circuitry in the Power
Manager keeps the part in a reset state until the oscillator connected to XIN0 has settled. If XIN0
receives an external clock, no such settling delay is applied.
On system start-up, the PLLs are disabled. All clocks to all modules are running. No clocks have
a divided frequency, all parts of the system recieves a clock with the same frequency as the
XIN0 clock.
9.2 Fetching of initial instructions
After reset has been released, the AVR32AP CPU starts fetching instructions from the reset
address, which is 0xA000_0000. This address lies in the P2 segment, which is non-translated,
non-cacheable, and permanently mapped to the physical address range 0x0000_0000 to
0x2000_0000. This means that the instruction being fetched from virtual address 0xA000_0000
is being fetched from physical address 0x0000_0000. Physical address 0x0000_0000 is
mapped to EBI SRAM CS0. This is the external memory the device boots from.
AT32AP7001
The code read from the SRAM CS0 memory is free to configure the system to use for example
the PLLs, to divide the frequency of the clock routed to some of the peripherals, and to gate the
clocks to unused peripherals.

11. Errata
11.1 Rev. C
AT32AP7001
1. SPI FDIV option does not work
Selecting clock signal using FDIV = 1 does not work as specified.
Fix/Workaround
Do not set FDIV = 1.
2. SPI Chip Select 0 BITS field overrides other Chip Selects
The BITS field for Chip Select 0 overrides BITS fields for other Chip selects.
Fix/Workaround
Update Chip Select 0 BITS field to the relevant settings before transmitting with Chip Selects
other than 0.
3. SPI LASTXFER may be overwritten
When Peripheral Select (PS) = 0, the LASTXFER-bit in the Transmit Data Register (TDR)
should be internally discared. This fails and may cause problems during DMA transfers.
Transmitting data using the PDC when PS=0, the size of the transferred data is 8- or 16-bits.
The upper 16 bits of the TDR will be written to a random value. If Chip Select Active After
Transfer (CSAAT) = 1, the behavior of the Chip Select will be unpredictable.
Fix/Workaround
- Do not use CSAAT = 1 if PS = 0
- Use GPIO to control Chip Select lines
- Select PS=1 and store data for PCS and LASTXFER for each data in transmit buffer.
4. SPI LASTXFER overrides Chip Select
The LASTXFER bit overrides Chip Select input when PS = 0 and CSAAT is used.
Fix/Workaround
- Do not use the CSAAT
- Use GPIO as Chip Select input
- Select PS = 1. Transfer 32-bit with correct LASTXFER settings.
5. MMC data drite operation with less than 12 bytes is impossible.
The Data Write operation with a number of bytes less than 12 is impossible
Fix/Workaround
The PDC counters must always be equal to 12 bytes for data transfers lower than 12 bytes.
The BLKLEN or BCNT field are used to specify the real count number.
6. MMC SDIO interrupt only works for slot A
If 1-bit data bus width and on other slots than slot A, the SDIO interrupt can not be captured.
32015AS–AVR32–02/07
Fix/Workaround
Use slot A.
38
AT32AP7001
7. PSIF TXEN/RXEN may disable the transmitter/receiver
Writing a '0' to RXEN will disable the receiver. Writing '0' to TXEN will disable the transmitter.
Fix/Workaround
When accessing the PS/2 Control Register always write '1' to RXEN to keep the receiver
enabled, and write '1' to TXEN to keep the transmitter enabled.
8. PSIF TXRDY interrupt corrupts transfers
When writing to the Transmit Holding Register (THR), the data will be transferred to the data
shift register immediately, regardless of the state of the data shift register. If a transfer is
ongoing, it will be interrupted and a new transfer will be started with the new data written to
THR.
Fix/Workaround
Use the TXEMPTY-interrupt instead of the TXRDY-interrupt to update the THR. This
ensures that a transfer is completed.
9. PWN counter restarts at 0x0001
The PWN counter restarts at 0x0001 and not 0x0000 as specified. Because of this the first
PWM period has one more clock cycle.
Fix/Workaround
- The first period is 0x0000, 0x0001, ..., period
- Consecutive periods are 0x0001, 0x0002, ..., period
10. PWM channel interrupt enabling triggers an interrupt
When enabling a PWM channel that is configured with center aligned period (CALG=1), an
interrupt is signalled.
Fix/Workaround
When using center aligned mode, enable the channel and read the status before channel
interrupt is enabled.
11. PWM update period to a 0 value does not work
It is impossible to update a period equal to 0 by the using the PWM update register
(PWM_CUPD).
Fix/Workaround
Do not update the PWM_CUPD register with a value equal to 0.
12. PWM channel status may be wrong if disabled before a period has elapsed
Before a PWM period has elapsed, the read channel status may be wrong. The CHIDx-bit
for a PWM channel in the PWM Enable Register will read '1' for one full PWM period even if
the channel was disabled before the period elapsed. It will then read '0' as expected.
Fix/Workaround
Reading the PWM channel status of a disabled channel is only correct after a PWM period
32015AS–AVR32–02/07
13. TWI transfer error without ACK
If the TWI does not receive an ACK from a slave during the address+R/W phase, no bits in
the status register will be set to indicate this. Hence, the transfer will never complete.
39
11.2 Rev. B
11.3 Rev. A
AT32AP7001
Fix/Workaround
To prevent errors due to missing ACK, the software should use a timeout mechanism to terminate the transfer if this happens.
Not sampled.
