Low-power, high-performance CMOS 8-bit microcontroller with 4KB ISP flash memory. The device uses Atmel high-density nonvolatile memory technology and is compatible with the industry-standard MCS®-51 instruction set.

An enhanced CPU core can fetch a single byte from memory every clock cycle and is capable of 20-MIPS throughput. The new CPU core runs at a much lower speed, greatly reducing power consumption.
