XR21V1412
2-CH FULL-SPEED USB UART
DECEMBER 2013
REV. 1.3.0
GENERAL DESCRIPTION
The XR21V1412 (V1412) is an enhanced 2-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 V1412 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 V1412 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 V1412 operates from a single 2.97 to 3.63 volt
power supply and has 5V tolerant inputs. The V1412
is available in a 32-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 XR21V1412.
