DESCRIPTION
The Philips microcontrollers described in this data sheet are
high-performance static 80C51 designs incorporating Philips’
high-density CMOS technology with operation from 2.7 V to 5.5 V.
They support both 6-clock and 12-clock operation.
The P8xC31X2/51X2 and P8xC32X2/52X2/54X2/58X2 contain
128 byte RAM and 256 byte RAM respectively, 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 devices are low power static designs which offer 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. Then the execution can be resumed from
the point the clock was stopped.

on-chip peripherals, see the P89C66x and P89C51Rx2 data sheets.
