Board summary:

  • Processor: Freescale i.MX27 (ARM9 @ 400MHz)
  • RAM: Mobile DDR. 64 to 256MB. 32 bits data bus. Default capacity will be either 64 or 128MB.
  • Flash: Mobile NAND. 256MB, 16 bits data bus.
  • Ethernet: onboard Physical (ready to use Ethernet 10/100Mbit link)
  • USB: High speed USB OTG (OnTheGo) with onboard Physical (ready to use USB OTG link)
  • USB: 1 High speed Host and 1 full speed USB Host ports (external PHY required)
  • RS232: onboard Physical (RS232 compatible interface)
  • FPGA: Xilinx Spartan 3A (50 to 400k gates, 200k default)
  • Supplies: high end DC/DC converters and LDOs on board. Only one external supply of 3.3V required.
  • Low power sleep mode (<10mW)
  • Mechanical dimensions: ~60x45mm

All the i.MX27 peripherals (LCD, 2xSDIO, 3xSPI, 6xSerial, I2C, CSI, 3xUSB, keypad, PWM, etc...) and the FPGA signals can be accessed through two high density Hirose connectors like on the APF9328 board.

The APF27 module can be plugged on the APF27Dev docking board or your own custom devt board.
