1. 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 non-

volatile memory technology and is compatible with the industry-standard MCS-51

instruction set and pinout. The on-chip downloadable Flash allows the program mem-

ory to be reprogrammed in-system through an SPI serial interface or by a

conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU

with downloadable Flash on a monolithic chip, the Atmel AT89S8253 is a powerful

microcontroller which provides a highly-flexible and cost-effective solution to many

embedded control applications.
