On chip peripherals include USB 2.0 full speed device, SPI master andslave, two USARTs, three 16-bit timer counters, an 8-channel/ 10-bitanalog to digital converter, plus interrupt control and supevisoryfunctions noted above.

Atmel provides special FPGA logic that decodes and encodes thetraffic that flows between the FPGA and the CAP7E microcontroller.

The device can be programmed using existing third party tools. Thesame C compilers, RTOS, OSs, ICEs and IDEs used with Atmel's AT91SAMARM-based MCUs can be used with the CAPE. These include Atmel's freeGNU gcc C compiler, GNU gdb debugger, FreeRTOS.org real-time kernel, aswell as a host of commercially available tools.

Atmel's AT91CAP7E is available now and is priced as low as $6.95 inquantities of 10,000 units. For more information visit www.atmel.com/products/AT91CAP.
