General Description

THE CDP1851 and CDP1851C are CMOS programmable twoport I/Os designed for use as general-purpose I/O devices.

They are directly compatible with CDP1800-series microprocessors functioning at maximum clock frequency.

Each port can be programmed in either byte-I/O or bit-programmable modes for interfacing with peripheral devices such as printers and keyboards.

Overview

CDP1851, CDP1851C March 1997 CMOS Programmable I/O Interface.

Key Features

  • 20 Programmable I/O Lines.
  • Programmable for Operation in Four Modes: - Input - Output - Bidirectional - Bit-programmable.
  • Operates in Either I/O or Memory Space Ordering Information.
