SAM7XCxx_DevMaster Board

Now also my third DevMaster is finished. Again with a 32bit processor with ARM7 core.
Actually this time the SAM7XCxx_DevMaster and the LPC236x_DevMaster should develop at the same time around a direct comparison between these to permit, however NXP has some problems with the update on a corrected version of its MCU's. Like already with the previous DevMaster-boards probably remained due to the interface desires and compactness again only 'do-it-yourself'.
The result is in the following specified.

Technical data:

  • Atmel AT91SAM7XCxx CPU (AT91SAM7X64 ... A91SAM7XC256)
  • 18.432 MHz
  • USB 2.0 full-speed Device
  • Ethernet 10/100M by Davicom DM9161A plus Taimag RJLBC-060TC1
  • ARM7-JTAG Interface (switchable JTAG-InCircuitEmulation or JTAG-BoundaryScan)
  • MMC/SD-Card Slot
  • Header-pinning with USB / MMC-SD / DBGU / UART0 / UART1 / SPI1 / SSC / CAN / TwoWire / AD0..7 /
        PWM / PCK / NRST & ADVREF or all as PIOs
  • Power supply by header-pin or by USB

    The produced Header-pinning puts thus up to the Ethernet-interface all further pins of the MCU at the free disposal. And so all pins (up to the two USB pins PA2, PA7) can be used as desired as PIOs or UART,CAN,SPI,TWI,TIO,SSC, PCK,PWM,AD... for own ideas.
