The XR21V1410IL16-F is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with an USB interface. The USB interface is fully compliant to full speed USB 2.0 specification that supports 12Mbps USB data transfer rate. The USB interface also supports USB suspend, resume and remote wakeup operations. The V1410 operates from an internal 48MHz clock therefore no external crystal/oscillator is required like previous generation UARTs. With the fractional baud rate generator, any baud rate can accurately be generated using the internal 48MHz clock. The large 128-byte FIFO and 384-byte RX FIFO of the V1410 helps to optimize the overall data throughput for various applications. The automatic transceiver direction control feature simplifies both the hardware and software for half-duplex RS-485 applications. If required, the multidrop (9-bit) mode with automatic half-duplex transceiver control feature further simplifies typical multidrop RS-485 applications.
