CMOS single-chip 8-bit microcontrollers
80C528/83C528
DESCRIPTION
The 8XC528 single-chip 8-bit microcontroller
is manufactured in an advanced CMOS
process and is a derivative of the 80C51
microcontroller family. The 8XC528 has the
same instruction set as the 80C51. Three
versions of the derivative exist:
ROM
multi-source, two-priority-level, nested
interrupt structure, two serial interfaces
(UART and I
2
C-bus), and on-chip oscillator
and timing circuits.
In addition, the 8XC528 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.

This device provides architectural
enhancements that make it applicable in a
variety of applications in consumer, telecom
and general control systems, especially in
those systems which need large ROM and
RAM capacity on-chip.
