AT89LS53-12JC datasheet



The AT89LS53-12JC is a low-power, wide-voltage range, 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 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 AT89LS53 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications.
