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). Thedevice is manufactured using Atmel’s high density nonvolatile memory technology and is compatible with the industry standard MCS-51™ instruction set and pinout. Theon-chip Flash allows the program memory to be reprogrammed in-system or by a conventionalnonvolatile memory programmer. By combining a versatile 8-bit CPU withFlash on a monolithic chip, the Atmel AT89C51 is a powerful microcomputer whichprovides a highly flexible and cost effective solution to many embedded control applications.
