XR21V1414  
4-CH FULL-SPEED USB UART  
REV. 1.0.0  
JUNE 2009  
FEATURES  
GENERAL DESCRIPTION  
USB 2.0 Compliant Interface  
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.  
Supports 12 Mbps USB full-speed data rate  
Supports USB suspend, resume and remote  
wakeup operations  
Enhanced Features of each UART  
Data rates up to 12 Mbps  
Fractional Baud Rate Generator  
128 byte TX FIFO  
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.  
384 byte RX FIFO  
7, 8 or 9 data bits, 1 or 2 stop bits  
Automatic Hardware (RTS/CTS or DTR/DSR)  
The large 128-byte FIFO and 384-byte RX FIFO of  
the V1414 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  
Flow Control  
Automatic Software (Xon/Xoff) Flow Control  
Multidrop mode w/ Auto Half-Duplex  
Transceiver Control  
Multidrop mode w/ Auto TX Enable  
Half-Duplex mode  
further  
simplifies  
typical  
multidrop  
RS-485  
Sleep Mode with Remote Wake-up  
Selectable GPIO or Modem I/O  
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.  
Internal 48 MHz clock  
Single 2.97-3.63V power supply  
5V tolerant inputs  
Software drivers for Windows 2000, XP, Vista, and  
CE, as well as Linux and Mac are supported for the  
XR21V1414.  
48-pin TQFP package  
Virtual COM Port drivers  
APPLICATIONS  
Windows 2000, XP and Vista  
Windows CE 4.2, 5.0, 6.0  
Linux  
Portable Appliances  
External Converters (dongles)  
Battery-Operated Devices  
Cellular Data Devices  
Mac  
Factory Automation and Process Controls  
Industrial applications
