P83C524; P80C528; P83C528 8-bit Microcontrollers

P83C524; P80C528 P83C528 8-bit Microcontrollers 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 x 8 respectively 32 k x 8 read-only program memory, a volatile 512 bytes x 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 ms. Multiply and divide instructions require 3 s.
