The XR21V1414 (V1414) is an enhanced 4-channel
USB Universal Asynchronous Receiver and
Transmitter (UART). 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 V1414 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 V1414 helps to optimize the overall data
throughput for various applications. If required, the
multidrop mode and automatic RS-485 half-duplex
direction control feature further simplifies typical
multidrop RS-485 applications.
The V1414 operates from a single 2.97 to 3.63 volt
power supply and has 5V tolerant inputs. The V1414
is available in a 48-pin TQFP package.
WHQL certified software drivers for Windows 2000,
XP, Vista, 7, 8, and CE, as well as Linux and Mac are
supported for the XR21V1414.
