DESCRIPTION
The 87C528 single-chip 8-bit microcontroller is manufactured in an
advanced CMOS process and is a derivative of the 80C51
microcontroller family. The 87C528 has the same instruction set as
the 80C51. Three versions of the derivative exist:
83C528—32k bytes ROM
83C524—16k bytes ROM
80C528—ROMless version of the 83C528
87C528—32k bytes EPROM
83C524—16k bytes EPROM
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 87C528 contains a 32k
×
8 EPROM and the 87C524 contains a
16k x 8 EPROM. Both devices have 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 I
2
C-bus), and on-chip oscillator and timing circuits.
In addition, the 87C524/87C528 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.
