Product specification

P89C738; P89C739

1 FEATURES

• 80C51 CPU

• 64-kbyte on-chip Multiple Programming ROM

(MTP-ROM), expandable externally to 64 kbytes

program memory address space

• 512-byte on-chip RAM, expandable externally to

64 kbytes data memory address space

• P89C738 pin outs fully compatible to the standard

8051/8052

• 8-bit I/O ports for P89C738: 4 and P89C739: 6

• Full-duplex UART compatible with the standard 80C51

and the 8052

• Two standard 16-bit timers/event counters

• An additional 16-bit timer (functionally equivalent to the

Timer 2 of the 8052)

• On-chip Watchdog Timer (T3)

• 6-source and 6-vector interrupt structure with 2 priority

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

Watchdog Timer reset

• Wake-up from Power-down by external interrupt,

external or Watchdog Timer reset

• Packages,

– P89C738: DIP40, PLCC44 and QFP44

– P89C739: PLCC68 and QFP64

• Improved Electromagnetic Compatibility (EMC)

• Frequency range: 3.5 to 40 MHz

• ROM code protection.

2 GENERAL DESCRIPTION

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.
