AT89S2051-24PU DIP-20 24MHz Microcontroller

Low power, high performance CMOS 8-bit microcontroller with 2KB ISP flash memory. The device uses Microchip high-density non-volatile memory technology and is compatible with the industry standard MCS?-51 instruction set.

 

An advanced CPU core can retrieve a single byte from memory per clock cycle and has a 20-MIPS transfer rate. The new CPU core operates at a much lower speed, greatly reducing power consumption.
