Description

The AT87F55 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 pro-
