XR16L570 - SMALLEST 1.62V TO 5.5V UART

General Description

The XR16L570 (L570) is a 1.62 to 5.5 volt Universal Asynchronous Receiver and Transmitter (UART) with 5 volt tolerant inputs and a reduced pin count.

It is software compatible to industry standard 16C450, 16C550, ST16C580, ST16C650A, XR16C850 and XR16L580 UARTs.

Key Features

  • to support today’s high bandwidth data communication needs. The enhanced features include 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.
