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. 3286L–MICRO–8/08 8-bit Microcontroller with 12K Bytes Flash and 2K Bytes EEPROM AT89S8253 |
