8-bit Microcontroller with 8kB In-System Programmable Flash

The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured 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 in-system programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller which provides a highly-flexible and cost-effective solution to many embedded control applications.

Features:

  • Compatible with MCS-51® Products
  • 8K Bytes of In-System Programmable (ISP) Flash Memory
    • Endurance: 1000 Write/Erase Cycles
  • 4.0V to 5.5V Operating Range
