AT91R40008-66AU Family Name, Microchip AT91R40008-66AU, 32bit ARM Microcontroller, AT91, 75MHz, 256 kB Flash, 100-Pin LQFP

The AT91R40008 microcontroller is a member of the Atmel AT91 16/32-bit microcon-roller 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. Furthermore, it features 256K bytes of on-chip SRAM and a large number of internally banked registers, resulting in very fast excep-ion handling, and making the device ideal for real-time control applications.
