Product Summary
The AT89S52-24PU is an 8-bit microcontroller with 8K bytes in-system programmable flash. It is manufactured using Atmels high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pinout. The AT89S52-24PU allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, the AT89S52-24PU is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications.
