The AT89S8252 is a low-power, high-performance CMOS 8-bit microcontroller with 8K
bytes of downloadable Flash programmable and erasable read-only memory and 2K
bytes of EEPROM. The device is manufactured using Atmels high-density nonvolatile
memory technology and is compatible with the industry-standard 80C51 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 AT89S8252 is a powerful microcontroller, which
provides a highly-flexible and cost-effective solution to many embedded control
applications.
