DESCRIPTION
The Philips 80C31/32 is a high-performance static 80C51 design
fabricated with Philips high-density CMOS technology with operation
from 2.7 V to 5.5 V.
The 80C31/32 ROMless devices contain a 128 × 8 RAM/256 × 8
RAM, 32 I/O lines, three 16-bit counter/timers, a six-source,
four-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.
In addition, the device is a low power static design which offers a
wide range of operating frequencies down to zero. Two software
selectable modes of power reduction—idle mode and power-down
mode are available. 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. Since the design is static, the clock can be stopped
without loss of user data and then the execution resumed from the
point the clock was stopped.
