DESCRIPTION
The Philips 8XC550 is a high-performance microcontroller fabricated
with Philips high-density CMOS technology. This 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 CMOS 8XC550 has the
same instruction set as the 80C51.
The 8XC550 contains a 4k
× 8 EPROM (87C550)/ROM
(83C550)/ROMless (80C550 has no program memory on-chip), a
128
× 8 RAM, 8 channels of 8-bit A/D, four 8-bit ports (port 1 is input
only), a watchdog timer, two 16-bit counter/timers, a seven-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 an on-chip oscillator and clock circuits.
In addition, the 8XC550 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.
