AT89C1051 Datasheet 8-bit Microcontroller With 1k Byte Flash

Manufacturer: Atmel (now Microchip Technology)

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The AT89C1051 is a low-voltage, high-performance CMOS 8-bit microputer with 1K byte of Flash programmable and erasable read only memory (PEROM).

The device is manufactured using Atmel’s high density nonvolatile memory technology and is patible with the industry standard MCS-51™ instruction set.

By bining a versatile 8-bit CPU with Flash on a monolithic chip, the Atmel AT89C1051 is a powerful microputer which provides a highly flexible and cost effective solution to many embedded control applications.

Key Features
