XR16L651 - 2.25V TO 5.5V UART

General Description

The XR16L6511 (651) is a 2.25 to 5.5 volt Universal Asynchronous Receiver and Transmitter (UART) with 5 volt tolerant inputs.

This device supports Intel and Motorola data bus interfaces and is software compatible to industry standard 16C450, 16C550, ST16C580 and ST16C650A UARTs.

Key Features

  • to support today’s highly demanding data communication needs. The enhanced features include automatic hardware and software flow control, selectable TX and RX trigger levels, and wireless infrared (IrDA) encoder/decoder. The device provides a new capability to give user the ability to program the wireless infrared encoder output pulse width, hence reducing the power consumption of a handheld unit. The XR16L651 device comes in a small 7x7x1mm 48-pin TQFP package in both the commercial and industr.
