XR16C850IJ-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C850IJ-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features 128-byte transmit and receive FIFOs with counters to optimize data loading and unloading from the controlling CPU. The device supports data rates up to 2.25 Mb/s and operates within a supply voltage range of 2.97 V to 5.5 V, typically at 3.3 V or 5 V. It draws between 2.7 mA and 4 mA during operation. Designed for surface-mount installation, it is housed in a TQFP-48 package and functions within an operating temperature range of 0°C to +70°C.
