Description

The AT89C52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K

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 80C51 and 80C52 instruction set and pinout.

The on-chip Flash allows the program memory to be reprogrammed in-system or by a

conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU

with Flash on a monolithic chip, the Atmel AT89C52 is a powerful microcomputer

which provides a highly flexible and cost effective solution to many embedded control

applications.
