XR16C850CM-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16C850CM-F is a single-channel Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device features a data rate capability of up to 2.25 Mb/s and includes 128 bytes of transmit and receive FIFO storage with counters to optimize CPU data loading and unloading. It draws a typical operating current of 2.7 mA at 3.3 V and 4 mA at 5 V. 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.
