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.
