80C32/87C52
DESCRIPTION
The Philips 80C32/87C52 is a high-performance microcontroller
fabricated with Philips high-density CMOS technology. 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 87C52 contains an 8k
×
8 EPROM and the 80C32 is ROMless.
Both contain a 256
×
8 RAM, 32 I/O lines, three 16-bit
counter/timers, a six-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 80C32/87C52 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.
See 80C52/80C54/80C58 datasheet for ROM device specifications.
