Enhanced 1-CH Full-Speed USB UART

XR21B1411

Single Channel USB UART with Industry’s Smallest Package

and Optimized Software Drivers

The XR21B1411 (B1411) is an enhanced Universal Asynchronous Receiver and

Transmitter (UART) with a USB interface. The USB interface is fully compliant to

FꢀATURꢀS

• ±15kV HBM ESD on

USBD+/USBD-

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.

• USB 2.0 Compliant Interface

 Supports 12 Mbps USB

full-speed data rate

The B1411 operates from an internal clock that is programmable to 6, 12, 24 or

48 MHz. Therefore, no external crystal / oscillator is required as in previous

generation UARTs. With the fractional baud rate generator, any baud rate up to

12 Mbps can be accurately generated using the internal clock.

 Supports USB suspend, resume

and remote wakeup operations

• Enhanced UART Features

 Data rates up to 12 Mbps

 Fractional Baud Rate Generator

 128 byte TX FIFO

The large 128-byte TX FIFO and 384-byte RX FIFO of the B1411 help 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.

 384 byte RX FIFO

 7, 8 or 9 data bits

 1 or 2 stop bits

 Odd, even, mark, space

or no parity

The Vendor ID, Product ID, bus-powered mode, self-powered mode, remote

wakeup support or maximum power consumption values, as well as default

baud rate settings can be programmed using the on-board OTP through the

USBD+ / USBD- pins.

 Automatic Hardware (RTS/CTS

or DTR/DSR) Flow Control

 Automatic Software (Xon/Xoff)

Flow Control

 Multidrop mode

The B1411 operates from a single 5V power supply and is available in a 16-pin

QFN package.

 Auto Transceiver Control

 Half-Duplex mode

Software drivers for Windows 7, 2000, XP, Vista, and CE, as well as Linux and

Mac are supported for the XR21B1411.

 Selectable GPIO or Modem I/O

• Internal 48 MHz clock with

clock divisors programmable

down to 6 MHz

• Single 5V power supply

• 16-pin QFN package

• Virtual COM Port drivers

 Windows 7, 2000, XP and

Vista

 Windows CE 4.2, 5.0, 6.0

 Linux

 Mac
