General Description

The W78C51D microcontroller supplies a wider frequency and supply voltage range than most 8-bit microcontrollers on the market.

It is compatible with the industry standard 80C51 microcontroller series.

The W78C51D contains four 8-bit bidirectional parallel ports, one extra 4-bit bit-addressable I/O port (Port 4) and two additional external interrupts ( INT2 , INT3 ), two 16-bit timer/counters, one watchdog timer and a serial port.
