Microchip AT91M40800-33AU ARM Microcontroller, 100-Pin LQFP

The Microchip ARM thumb microcontroller is a member of the Atmel AT91 microcontroller family, which is based on the ARM7TDMI processor core. This processor has a high-performance 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.
