|USB to Quad UART Module Features|
|Product Name||USB to quad UART module|
|SPec.||can support four 5-wire serial port|
|Main function||XR21V1414（V1414）is an enhanced convert chip to convert USB to 4-ch UART. It can completly compatible with full speed USB2.0 and support USB data transferring rate up to 12Mbps. It can also support suspend, restore and remote wakeup operations. XR21V1414 works at speed of 48MHz but no need any external crystal. Internal separate baud rate generator runs at speed of 48MHz for precise baud rate generating. XR21V1414 is available for 128 bytes sending FIFO and 384 bytes receiving, which can improve data throughout and reduce CPU consumption. Can support auto transceiving direction control, simplified half-duplex RS485 application in both hardware and software. In multi-point (9-bit) mode, it can support auto half-duplex transceiving control fuction which simplified RS485 application. XR21V1414 working voltage ranges from 2.97V to 3.63V, 5V withstand input, and it is TQFP-48 package|
