ATMEL AT89S8253-24JU

Product Overview

The AT89S8253-24JU is a 8-bit low-power high-performance CMOS Microcontroller with 12kB of in-system programmable (ISP) flash program memory and 2kB of EEPROM data memory. The device is manufactured using Atmel's high-density nonvolatile memory technology and is compatible 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. 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.
