Description

The AT89LV51 is a low-voltage, high-performance CMOS 8-bit microcomputer with

4K bytes of Flash Programmable and Erasable Read Only Memory. The device is

manufactured using Atmel’s high density nonvolatile memory technology and is com-

patible with the industry standard MCS-51™ instruction set and pinout. The on-chip

Flash allows the program memory to be reprogrammed in-system or by a conven-

tional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash

on a monolithic chip, the Atmel AT89LV51 is a powerful microcomputer which pro-

vides a highly flexible and cost effective solution to many embedded control applica-

AT89LV51

tions. The AT89LV51 operates at 2.7 volts up to 6.0 volts.
