AT89S8252规格书详情
Description
The AT89S8252 is a low-power, high-performance CMOS 8 bit microcomputer with 8K bytes of Downloadable Flash programmable and erasable read only memory and 2K bytes of EEPROM. The device is manufactured using Atmel’s high density nonvolatile memory technology and is compatible with the industry standard 80C51 in struction 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 conven tional nonvolatile memory programmer. By combining a versatile 8 bit CPU with Downloadable Flash on a monolithic chip, the Atmel AT89S8252 is a powerful micro
computer which provides a highly flexible and cost effective solution to many embedded control applications.
