CMOS LOW-VOLTAGE SINGLE-CHIP 8-BIT MICROCONTROLLER
The 80CL31/80CL51 is a high-performance microcontroller fabricated with high-density
CMOS technology. The instruction set is based on that the 80C51.The 80CL51 is general
purpose microcontroller especially suited for battery powered applications. The device has
low power consumption and a wide range of supply voltage.
The 80CL51 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.
