XR21V1414  
4-CH FULL-SPEED USB UART  
REV. 1.3.0  
DECEMBER 2013  
FEATURES  
GENERAL DESCRIPTION  
USB 2.0 Compliant, Full-speed (12 Mbps)  
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 USB suspend, resume and remote  
wakeup operations  
± 5 kV HBM ESD protection on USB data pins  
± 2 kV HBM ESD protection on all other pins  
Enhanced Features of each UART  
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.  
UART data rates up to 12 Mbps  
Fractional Baud Rate Generator  
128 byte TX FIFO  
384 byte RX FIFO  
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.  
7, 8 or 9 data bits  
1 or 2 stop bits  
Odd, even, mark, space, or no parity  
Automatic Hardware (RTS/CTS or DTR/DSR)  
Flow Control  
Automatic Software (Xon/Xoff) Flow Control  
Multidrop mode  
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.  
Auto RS-485 Half-Duplex Control  
Half-Duplex mode  
WHQL certified software drivers for Windows 2000,  
XP, Vista, 7, 8, and CE, as well as Linux and Mac are  
supported for the XR21V1414.  
Selectable GPIO or Modem I/O  
Internal 48 MHz clock  
APPLICATIONS  
Single 3.3V power supply  
5V tolerant inputs  
Portable Appliances  
External Converters (dongles)  
Battery-Operated Devices  
Cellular Data Devices  
48-pin TQFP package  
Virtual COM Port WHQL certified drivers  
Windows 2000, XP Vista, Win7 and Win8  
Windows CE 4.2, 5.0, 6.0, 7.0  
Factory Automation and Process Controls  
Industrial applications
