                     Based on Atmel At9200 ARM9 CPU
                         Embedded Sytem Design

overview
The Atmel AT91RM9200 is a complete system-on-chip built around the
ARM920T ARM Thumb pro-cessor. It incorporates a rich set of system and
application peripherals and standard interfaces in order to provide a single-chip
solution for a wide range of compute-intensive applications that require
maximum functionality at minimum power consumption at lowest cost.
