XR16M752IL32-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16M752IL32-F is a high-performance dual universal asynchronous receiver and transmitter (UART) manufactured by MaxLinear. It operates from a supply voltage of 1.62V to 3.63V and features two independent UART channels, each equipped with 64-byte transmit and receive FIFOs. The device supports data rates up to 16 Mbps at 3.3V using a 4X sampling rate. It includes a programmable fractional baud rate generator, automatic hardware flow control via RTS/CTS, and software flow control via Xon/Xoff. The component is housed in a 32-pin QFN package and is designed for industrial temperature ranges.
