DESCRIPTION
The Philips 80C31/80C51/87C51 is a high-performance
microcontroller fabricated with Philips high-density CMOS
technology. The CMOS 8XC51 is functionally compatible with the
NMOS 8031/8051 microcontrollers. The Philips CMOS technology
combines the high speed and density characteristics of HMOS with
the low power attributes of CMOS. Philips epitaxial substrate
minimizes latch-up sensitivity.
The 8XC51 contains a 4k
×
8 ROM (80C51) EPROM (87C51), a 128
×
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.
In addition, 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.
