W78L52 Overview
The W78L52 microcontroller supplies a wider frequency and supply voltage range than most 8-bit microcontrollers on the market. It is patible with the industry standard 80C52 microcontroller series. The W78L52 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 ), three 16-bit timer/counters, one watchdog timer and a...
