AT89S8253 Datasheet 8-bit Microcontroller

Manufacturer: Atmel (now Microchip Technology)

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

General Description

The AT89S8253 is a low-power, high-performance CMOS 8-bit microcontroller with 12K bytes of In-System Programmable (ISP) Flash program memory and 2K bytes of EEPROM data memory.

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

The on-chip downloadable Flash allows the program memory to be reprogrammed in-system through an SPI serial interface or by a conventional nonvolatile memory programmer.
