ATMEL AT89S52 8-bit Microcontroller 8051 SMD TQFP 44-Pin

The ATMEL AT89S52-24AU is an 8-bit, low-power, high-performance CMOS microcontroller with 8kB of in-system programmable (ISP) Flash memory. Manufactured using Atmel's high-density non-volatile memory technology, it is compatible with the industry-standard 80C51 instruction set and pinout, making it a versatile solution for a wide range of embedded control applications.

This powerful device combines a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, providing a highly flexible and cost-effective solution to many embedded control applications. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional non-volatile memory programmer, offering exceptional flexibility during development and deployment.
