UM6520A - Peripheral Interface Adapter

Download the UM6520A datasheet PDF. This datasheet also covers the UM6520 variant, as both devices belong to the same peripheral interface adapter family and are provided as variant models within a single manufacturer datasheet.

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.
