Description
The AT87F52 is a low-power, high-performance CMOS 8-bit microcomputer with 8K
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 80C51 and 80C52 instruction set and pinout. The on-chip Quick-
Flash allows the program memory to be user programmed by a conventional nonvola-
tile memory programmer. By combining a versatile 8-bit CPU with QuickFlash on a
monolithic chip, the Atmel AT87F52 is a powerful microcomputer which provides a
highly flexible and cost effective solution to many embedded control applications.
