XR21B1424 Enhanced 4-Ch Full-Speed USB UART General Description The XR21B1424 is an enhanced Universal Asynchronous Receiver and Transmitter (UART) bridge to USB interface. The USB interface is fully compliant to the USB 2.0 (Full-Speed) specification with 12 Mbps USB data transfer rate. The USB interface also supports USB suspend, resume and remote wakeup operations. The USB Vendor ID, Product ID, power mode, remote wakeup support, maximum power, and numerous other settings may be programmed in the on-chip OTP memory via the USB interface. The XR21B1424 includes an internal oscillator and does not require an external crystal/oscillator. Any UART baud rate from 300 bps to 12 Mbps may be generated with this internal clock and the fractional baud rate generator.
