Microcontroller

with 8K Bytes

QuickFlash^™

Description

The AT87LV52 is a low-voltage, high-performance CMOS 8-bit microcomputer with

8K bytes of QuickFlash one-time programmable (OTP) read only memory. The device

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

compatible with the industry standard MCS-51^™instruction set and pinout. The on-

chip QuickFlash allows the program memory to be user programmed by a conven-

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

QuickFlash on a monolithic chip, the Atmel AT87LV52 is a powerful microcomputer

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

AT87LV52
