W78C51D Datasheet 8-bit Microcontroller

Manufacturer: Winbond

Overview: Preliminary W78C51D 8-BIT MICROCONTROLLER GENERAL.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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

It is patible 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.

Key Features

  • Fully static design.
  • Supply voltage of 4.5V to 5.5V.
  • DC-40 MHz operation.
  • 128 bytes of on-chip scratchpad RAM.
  • 4K bytes of on-chip mask ROM.
  • 64K bytes program memory address space.
  • 64K bytes data memory address space.
  • Four 8-bit bidirectional ports.
  • Two 16-bit timer/counters.
  • One full duplex serial port.
  • Seven-source, two-level interrupt capability.
  • One extra 4-bit bit-addressable I/O por.
