Description

The AT87F55WD is a low-power, high-performance CMOS 8-bit microcomputer with

20K bytes of QuickFlash one-time programmable (OTP) read only memory and 256

bytes of RAM. 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 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 monolithic chip, the Atmel AT87F55WD is a

powerful microcomputer which provides a highly-flexible and cost-effective solution to

many embedded control applications.
