XR16M654IL48-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16M654IL48-F is a quad universal asynchronous receiver/transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features four independent UART channels, each equipped with 64-byte transmit and receive FIFOs that support programmable trigger levels. The device supports data rates up to 16 Mb/s and operates within a supply voltage range of 1.62 V to 3.63 V, compatible with 1.8 V, 2.5 V, and 3.3 V systems. It accommodates Intel and Motorola bus protocols and includes automatic hardware and software flow control. The component is housed in a QFN-48 package for surface-mount installation and functions reliably across an operating temperature range of -40°C to +85°C.
