Description  
The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4  
Kbytes 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 conventional 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  
applications.
