AT91SAM7A2 Description
The AT91SAM7A2 is based on the ARM7TDMI embedded processor. 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.
