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:
83C528 — 32k bytes mask programmable
ROM
80C528 — ROMless version of the
83C528
87C528 — 32k bytes EPROM (described
in a separate data sheet)
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.
The 8XC528 contains a 32k × 8 ROM
(83C528), a 512 × 8 RAM, four 8-bit I/O
ports, two 16-bit timer/event counters
(identical to the timers of the 80C51), a 16-bit
timer (identical to the timer 2 of the 80C52), a
watchdog timer with a separate oscillator, a
multi-source, two-priority-level, nested
interrupt structure, two serial interfaces
(UART and I2C-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.
