Product Description

The ATMEL AT89S52-24PU DIP-40 Microcontroller 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 80S51 and 80S52 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 AT89S52 is a powerful microcomputer which provides a highly flexible and cost-effective solution to many embedded control applications.
