Features
Description
The AT89C55 is a low-power, high-performance CMOS 8-bit microcomputer with 20K
bytes of Flash programmable and erasable read only memory. The device is manu-
factured using Atmel’s high density nonvolatile memory technology and is compatible
with the industry standard 80C51 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 AT89C55 is a powerful microcomputer which provides a highly flexible
and cost effective solution to many embedded control applications.
