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-  
AT89C51  
cations.
