XR21V1410
1-CH FULL-SPEED USB UART
JANUARY 2014
REV. 1.4.0
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 as
in 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 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.
The V1410 operates from a single 2.97 to 3.63 volt
power supply and has 5V tolerant inputs. The V1410
is available in a 16-pin QFN package.
WHQL certified software drivers for Windows 2000,
XP, Vista, 7, 8 and CE, as well as Linux and Mac are
supported for the XR21V1410.
