MaxLinear, Inc. UARTs (Universal Asynchronous Receiver Transmitter) XR16M890IM48TR-F

The XR16M890IM48TR-F is a single-channel Universal Asynchronous Receiver and Transmitter (UART) designed for versatile applications in mixed voltage environments. It features integrated level shifters and 128 bytes of transmit and receive FIFOs, allowing it to interface with devices operating at different voltage levels without the need for external shifters. The device supports data rates of up to 24 Mbps and includes an independent TX/RX baud rate generator, enabling the transmitter and receiver to operate at different baud rates. This UART also offers programmable transmit and receive FIFO trigger levels, automatic hardware and software flow control, and a sleep mode for reduced power consumption. Its Auto RS-485 half-duplex direction control simplifies hardware and software requirements for RS-485 applications. The device is compatible with a 16550 register set and provides onboard diagnostics through an internal loopback capability. The XR16M890IM48TR-F operates within a supply voltage range of 1.62V to 3.63V and is housed in a 48-pin TQFP package, making it suitable for various applications, including personal digital assistants, cellular phones, and battery-operated devices.
