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
High-performance 32-bit RISC Architecture
High-density 16-bit Instruction Set
Leader in MIPS/Watt
