DESCRIPTION
The Philips 80C851/83C851 is a
high-performance microcontroller fabricated
with Philips high-density CMOS technology.
The 80C851/83C851 has the same
instruction set as the 80C51. The Philips
CMOS technology combines the high speed
and density characteristics of HMOS with the
low power attributes of CMOS. The Philips
epitaxial substrate minimizes latch-up
sensitivity.
The 80C851/83C851 contains a 4k
×
8 ROM
with mask-programmable ROM code
protection, a 128
×
8 RAM, 256
×
8
EEPROM, 32 I/O lines, two 16-bit
counter/timers, a seven-source, five vector,
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 80C851/83C851 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 and
EEPROM contents but freezes the oscillator,
causing all other chip functions to be
inoperative.
