UART series features USB 2.0 compliant bus interface

The series consists of three devices, which is compliant to the USB 2.0 specification. The XR21V1410/V1412/V1414 have differentiated features, which include the smallest packaging options, optimized software drivers, and support large FIFO sizes delivering flexible and proven design options to system architects.

The XR21V1410/V1412/V1414 series targets a large cross-section of embedded and consumer applications. The XR21V1410, XR21V1412, and XR21V1414 have a USB slave 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.
