供应商器件封装 48-TQFP(7x7) The XR21V1414 is an enhanced 4-channel 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 XR21V1414 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 Tx FIFO and 384-byte RX FIFO of the XR21V1414 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. The multidrop (9-bit) mode with automatic half-duplex transceiver control feature further simplifies typical multidrop RS-485 applications.
The XR21V1414  operates from a single 2.97 to 3.63 volt power supply and has 5V tolerant inputs.
Software drivers for Windows 2000, XP, Vista, 7, 8, and CE, as well as Linux and Mac are supported for the XR21V1414. For UART technical support or to obtain an IBIS model for this product, please email Exar's UART Technical Support group.
