UM6520A Datasheet Peripheral Interface Adapter

Manufacturer: UMC

Overview: (l)UMC UM6520 / UM6520A Peripherald",',,""''"'"''''''''.''''' Interface.

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

General Description

The UM6520/A peripheral Interface Adapter (PIA) is designed to provide a broad range of peripheral control to microcomputer systems.

Control of peripheral devices is accomplished through two 8-bit bi-directional I/O ports.

Each I/O line may be programmed to be either an input or an output.

Key Features

  • Direct replacement for Motorola MC6820.
  • Single +5V power supply.
  • Two 8-bit bi-directional I/O ports with individual data direction control.
  • CMOS-compatible peripheral port A lines.
  • Automatic "handshake. ' control of data transfers.
  • Programmable interrupt capability.
  • Automatic initialization on power up.
  • 1 and 2 MHz versions General.
