The AT89C2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with

2K Bytes of Flash programmable and erasable read only memory (PEROM). The

device is manufactured using Atmel’s high density nonvolatile memory technology

and is compatible with the industry standard MCS-51™ instruction set. By combining

a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C2051 is a powerful

microcomputer which provides a highly flexible and cost effective solution to

many embedded control applications.-The AT89C2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with
