DESCRIPTION
The Philips 8XC51/31 is a high-performance static 80C51 design
fabricated with Philips high-density CMOS technology with operation
from 2.7V to 5.5V.
The 8XC51/31 contains a 4k
8 ROM, a 128
8 RAM, 32 I/O lines,
three 16-bit counter/timers, a six-source, four-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 is a low power static design which offers a
wide range of operating frequencies down to zero. Two software
selectable modes of power reduction--idle mode and power-down
mode are available. 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. Since the design is static, the clock can be stopped
without loss of user data and then the execution resumed from the
point the clock was stopped.
SELECTION TABLE
For applications requiring more ROM and RAM,
see the 8XC52/54/58/80C32, 8XC51FA/FB/FC/80C51FA,
and 8XC51RA+/RB+/RC+/80C51RA+ data sheet.
