The P89C738 and P89C739 (hereafter generally referred to as P89C738 unless the P89C739 is specifically mentioned) are 8-bit 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 kbytes 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.
