The high-performance, low-power Atmel 8-bit AVR RISC-based microcontroller combines 2KB of programmable flash memory, 32 general purpose registers, a keyboard interrupt, and an analog comparator. The device supports throughput of 4 MIPS at 4 MHz and operates between 2.7-5.5 volts.

By accessing two independent registers in a single clock cycle, the device achieves throughputs approaching 1 MIPS per MHz, balancing power consumption and processing speed.
