QuickFlash™

Description

The AT87F51RC is a low-power, high-performance CMOS 8-bit microcomputer with

32K bytes of QuickFlash one-time programmable (OTP) read only memory and 512

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
