DESCRIPTION
The Philips 8XC453 is an I/O expanded single-chip microcontroller
fabricated with Philips high-density CMOS technology. Philips
epitaxial substrate minimizes latch-up sensitivity.
The 8XC453 is a functional extension of the 87C51 microcontroller
with three additional I/O ports and four I/O control lines. The 8XC453
is available in 68-pin LCC packages. Four control lines associated
with port 6 facilitate high-speed asynchronous I/O functions.
The 87C453 includes an 8k
×
8 EPROM, a 256
×
8 RAM, 56 I/O
lines, two 16-bit timer/counters, a seven source, two priority level,
nested interrupt structure, a serial I/O port for either a full duplex
UART, I/O expansion, or multi-processor communications, and
on-chip oscillator and clock circuits.
The 87C453 has two software selectable modes of reduced activity
for further power reduction; idle mode and power-down mode. Idle
mode freezes the CPU while allowing the RAM, timers, serial port,
and interrupt system to continue functioning. Power-down mode
freezes the oscillator, causing all other chip functions to be
inoperative while maintaining the RAM contents.
