2 GENERAL DESCRIPTION
The P83C524 and P83C528 single-chip 8-bit
microcontrollers are manufactured in an advanced CMOS
process and are derivatives of the PCB80C51
microcontroller family. These devices provide architectural
enhancements that make them applicable in a variety of
applications in general control systems, especially in those
systems which need a large ROM and RAM capacity on
chip.
The P83C524 and P83C528 contain a non-volatile
16 k × 8 respectively 32 k × 8 read-only program memory,
a volatile 512 bytes × 8 read/write data memory, 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 8052), a multi-source, two-priority-level, nested
interrupt structure, two serial interfaces (UART and
bit-level I2C-bus), a watchdog timer (WDT) with a separate
oscillator, an on-chip oscillator and timing circuits. For
systems that require extra capability, the P83C524 and
P83C528 can be expanded using standard TTL
compatible memories and logic.
The device also functions as an arithmetic processor
having facilities for both binary and BCD arithmetic plus
bit-handling capabilities. The P83C524 and P83C528
have the same instruction set as the PCB80C51 which
consists of over 100 instructions: 49 one-byte, 46 two-byte
and 16 three-byte. With a 16 MHz crystal, 58% of the
instructions are executed in 750 ns and 40% in 1.5 µs.
Multiply and divide instructions require 3 µs.
