MaxLinear, Inc. UARTs (Universal Asynchronous Receiver Transmitter) XR16M2550IM48

The XR16M2550IM48 is a dual universal asynchronous receiver and transmitter (UART) designed for high performance and low voltage operation, supporting a voltage range of 1.62 to 3.63 volts. It features 16-byte transmit and receive FIFOs, allowing for efficient data handling. The device is pin-to-pin and software compatible with the ST16C2550, XR16L2550, and XR16V2550, making it suitable for easy integration into existing designs. This UART supports data rates of up to 16 Mbps at 3.3 V, 12.5 Mbps at 2.5 V, and 8 Mbps at 1.8 V, with independent programmable baud rate generators for each channel. Enhanced features include selectable FIFO trigger levels, automatic hardware (RTS/CTS) and software (Xon/Xoff) flow control, and a complete modem interface. The device also includes an internal loopback capability for system diagnostics and is available in both 48-pin TQFP and 32-pin QFN packages. Applications for the XR16M2550IM48 include portable appliances, telecommunication and Ethernet network routers, cellular data devices, and factory automation systems.
