CMOS SINGLE-CHIP 8-BIT MICROCONTROLLER
WITH 4K BYTES OF EPROM MEMORY
The 87C51 is the EPROM version of the 80C51. Microcontroller fabricated with high-
density CMOS technology. It contains 4K bytes of on chip Program memory that can be
electrically programmed The 80C51 contains a 4k x 8 ROM , a 128 x 8 RAM , 32 I/O lines,
two 16-bit counter/timers, a five-source, two-priority level nested interrupt structure, a
serial I/O port for either multi-processor communications, I/O expansion or full duplex
UART, and on-chip oscillator and clock circuits.
The device has two software selectable modes of power reduction
 idle mode and
power-down mode. The idle mode freezes the CPU while allowing the RAM, timers, serial
port, and interrupt system to continue functioning. The power-down mode saves the RAM
contents but freezes the oscillator, causing all other chip functions to be inoperative.
