8-bit Flash Microcontrollers

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 By NXP Semiconductors
