XR16L2551ILTR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16L2551ILTR-F is a dual Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It features 16-byte transmit and receive FIFOs for each channel, supporting data rates up to 3.125 Mb/s. The device operates within a supply voltage range of 2.25 V to 5.5 V, with typical operating voltages at 2.5 V, 3.3 V, and 5 V. Power consumption varies between 1 mA and 3 mA depending on the mode. It supports both Intel and Motorola bus interfaces and includes power-saving capabilities. The component is housed in a 32-lead QFN package measuring 5x5 mm and functions reliably across an industrial temperature range from -40°C to +85°C.
