Description
The AT87F51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K
bytes of QuickFlash Programmable 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 conventional nonvolatile
memory programmer. By combining a versatile 8-bit CPU with QuickFlash on a mono-
lithic chip, the Atmel AT87F51 is a powerful microcomputer which provides a highly
flexible and cost effective solution to many embedded control applications.
