Description

The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K

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 and pinout. The

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

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

Flash on a monolithic chip, the Atmel AT89C51 is a powerful microcomputer which

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

cations.
