Product Summary

The AT89C51-20PC is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash programmable and erasable read only memory (PEROM). The AT89C51-20PC is manufactured using Atmel high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 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 AT89C51-20PC is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.
