The AT91M55800A is a member of the Atmel AT91 16/32-bit microcontroller family,

which is based on the ARM7TDMI processor core. This processor has a high-perfor-

mance 32-bit RISC architecture with a high-density 16-bit instruction set and very low

power consumption. In addition, a large number of internally banked registers result in

very fast exception handling, making the device ideal for real-time control applications.

Utilizes the ARM7TDMI ® ARM® Thumb® Processor Core
