Notes
The P89C738 and P89C739 (hereafter generally referred
to as P89C738 unless the P89C739 is specifically
mentioned) are 8 8-bit Flash microcontrollers
manufactured in an advanced CMOS process and is a
derivative of the PCB80C51 microcontroller family. This
device provides architectural enhancements that make it
applicable in a variety of applications in general control
systems, especially in those systems which need a large
on-chip ROM and RAM capacity.
The P89C738 contains a non-volatile 64-kbyte Multiple
Programming ROM (MTP-ROM) program memory, a
volatile 512 bytes read/write data memory, four 8-bit I/O
ports (six for the P89C739), 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, one serial
interface (UART), a Watchdog Timer (T3), an on-chip
oscillator and timing circuits. For systems that require
extra capability, the P89C738 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 P89C738 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 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.
