Product Series Details

The XR21V1410, XR21B1411, XR21V1412, and XR21V1414 have a USB device interface, which is compliant with Full-Speed USB 2.0 specification.  All devices in the series support USB suspend, resume and remote wakeup operations.  All the devices share a common set of features including large FIFO sizes of 128-byte TX and 384-byte RX that optimize overall data throughput, automatic hardware (RTS/CTS or DTR/DSR) flow control, automatic software (Xon/Xoff) flow control, and multi-drop mode with auto half-duplex transceiver control.  In addition, none of the devices require an external crystal/oscillator which saves on board real estate.  The XR21B1411 offers +/- 15kV HBM ESD.

Availability and Additional Information

Complementing standard data sheets, user manuals are available for the evaluation boards.  All product documentation can be found on the individual product pages below.  An application note is available that outlines board design considerations for USB compliance.  Development tools are available now.  Information can be found on product pages for each device:
