Description
The AT89S53 is a low-power, high-performance CMOS 8-bit microcomputer with 12K bytes of downloadable Flash programmable and erasable read only memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pinout. The onchip 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 AT89S53 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.
