ENHANCED 1-CH FULL-SPEED USB UART

Overview

TopologyOther Topology
Switching frequency6-48 kHz
IC revision1.1.0

Description

The XR21B1411 (B1411) is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with a USB interface. The USB interface is fully compliantto Full Speed USB 2.0 specification that supports 12Mbps USB data transfer rate. The USB interface also supports USB suspend, resume and remote wakeup operations.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.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 AutomaticTransceiver 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 Vendor ID, Product ID, bus-powered mode, selfpowered mode, Remote Wakeup support or Maximum Power Consumption values, as well asdefault baud rate settings can be programmed using the on-board OTP through the USBD+ / USBD- pins.The B1411 operates from a single 5V power supply and is available in a 16-pin QFN package.WHQL certified software drivers for Windows 2000, XP, Vista, 7, and CE, as well as Linux and Mac are supported for the XR21B1411
