XR21V1410 1-CH FULL-SPEED USB UART www.DataSheet4U.com JUNE 2009 REV. 1.0.0 GENERAL DESCRIPTION The XR21V1410 (V1410) is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with a USB interface. The USB interface is fully compliant to Full Speed USB 2.0 specification that supports 12 Mbps 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.
