AT91M40400 Overview
The AT91M40400 is a member of the Atmel AT91 16/32-bit Microcontroller family which is based on the ARM7TDMI embedded processor. This processor has a highperformance 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...
