INTEGRATED CIRCUITS 80C31/80C32 80C51 8-bit microcontroller family 128/256 byte RAM ROMless low voltage (2.7 V–5.5 V), low power, high speed (33 MHz) Product specification IC28 Data Handbook 2000 Aug 07 Philips Semiconductors Philips Semiconductors 80C51 8-bit microcontroller family 128/256 byte RAM ROMless low voltage (2.7V–5.5V), low power, high speed (33 MHz) Product specification 80C31/80C32 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.
