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.
