Overview
W78L51 8-BIT MICROCONTROLLER GENERAL DESCRIPTION The W78L51 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 W78L51 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.
These peripherals are supported by a seven-source, two-level interrupt capability.
There are 128 bytes of RAM and an 4K byte mask ROM for application programs.
The W78L51 microcontroller has two power reduction modes, ...
