XR16M2750IM48TR-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The XR16M2750IM48TR-F is a dual universal asynchronous receiver-transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 1.62 V to 3.63 V and supports data rates up to 16 Mbps. The device features two independent UART channels, each equipped with a 32-byte FIFO buffer for efficient data handling. It integrates an internal oscillator and supports multiple communication protocols including RS-232 and RS-422. Additional functional blocks include automatic flow control, IrDA encoder/decoder capabilities, modem control signals, and false start bit detection. The component is housed in a 48-pin TQFP package measuring 7x7 mm.
