XR16L580 - SMALLEST 2.25V TO 5.5V UART

Description

The XR16L580 (L580) is a 2.25 to 5.5 volt Universal Asynchronous Receiver and Transmitter (UART) with 5 volt tolerant inputs and a reduced pin count.

It is pin-to-pin and software compatible to industry standard 16C450, 16C550, ST16C580, ST16C650A and XR16C850 UARTs.

Features

  • to support today’s high bandwidth data communication needs. The enhanced features include Intel or Motorola data bus interface to match your CPU interface, automatic hardware and software flow control to prevent data loss, selectable RX and TX trigger levels for more efficient interrupt service, wireless infrared (IrDA) encoder/decoder for wireless.
