Description

The AT89LV55 is a low-voltage, low-power CMOS 8-bit microcomputer with 20K

bytes of Flash programmable and erasable read only memory. The device is manu-

factured using Atmel’s high density nonvolatile memory technology and is compatible

with the industry standard 80C51 instruction set and pinout. The on-chip Flash allows

the program memory to be reprogrammed. By combining a versatile 8-bit CPU with

Flash on a monolithic chip, the Atmel AT89LV55 is a powerful microcomputer which

provides a highly-flexible and cost-effective solution to many embedded control appli-

cations.
