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.
