UM6522A - VERSATILE INTERFACE ADAPTER

Download the UM6522A datasheet PDF. This datasheet also covers the UM6522 variant, as both devices belong to the same versatile interface adapter family and are provided as variant models within a single manufacturer datasheet.

General Description

The UM6522 Versatile Interface Adapter (VIA) is a very flexible I/O control device.

In addition, this device contains a pair of very powerful 16-bit interval timers, a serialto-parallel/parallel-to-serial shift register and input data latching on the peripheral ports.

Key Features

  • Two 8-bit bidirectional I/O ports.
  • Two 16-bit programmable timer/counters.
  • Serial data port.
  • Single +5V power supply.
  • TTL compatible expect Port A.
  • CMOS compatible peripheral Port A lines.
  • Expanded "handshake" capability allows positive control of data transfers between processor and peripheral devices.
  • Latched output and input registers.
  • 1 MHz and 2 MHz operation General.
