FEATURES
· 80C51 CPU · 16 kbytes on-chip ROM, expandable
externally to 64 kbytes Program Memory address space
GENERAL DESCRIPTION
The P83C524 8-bit microcontroller is manufactured in an advanced CMOS process and is a derivative of the 80C51 microcontroller family. The P83C524 is a stand-alone high-performance microcontroller designed for use in real time applications such as instrumentation, industrial control, medium to high-end consumer applications and specific automotive control applications. The P83C524 contains a non-volatile 16K × 8 read-only program memory, a volatile 512 × 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), an on-chip oscillator and timing circuits, a watchdog timer (WDT) with a separate on-chip oscillator. For systems that require extra capability, the P83C524 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 has 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 16MHz crystal, 58% of the instructions are executed in 750ns and 40% in 1.5µs. Multiply and divide instructions require 3µs.
· 512 bytes on-chip RAM, expandable
externally to 64 kbytes Data Memory address space
· Four 8-bit I/O ports · Full-duplex UART compatible with the
standard 80C51 and the 8052
· Two standard 16-bit timer/counters · An additional 16-bit timer (functionally
equivalent to the timer 2 of the 8052)
· On-chip Watchdog Timer (WDT) with a
separate on-chip oscillator
· Bit-level I2C-bus hardware serial I/O Port · 7-source and 7-vector interrupt structure
with 2 prioirty levels
· Up to 3 external interrupt request inputs · Two programmable power reduction modes
(Idle and Power-down)
· Termination of Idle mode by any interrupt,
external or WDT (watchdog) reset
· Wake-up from Power-down by external
interrupt, external or WDT reset
· ROM code protection · XTAL frequency range: 1.2MHz to 16MHz · All packaging pin-outs fully compatible to
the standard 8051/8052.
