USB to Uart Module
Description:
USB to UART interface module allows all Forlinx development boards to switch interfaces
Features:
With the development of technology, there is a lot of use of RS232 serial communication in industry, but the application of commercial technology, has slowly replaced RS232 serial port using USB-to-UART technology, the vast majority of notebook computers already do not have serial port this thing, so you can add a USB re-serial chip on the circuit, you can successfully realize the USB communication protocol and standard UART serial communication protocol conversion
| USB to Quad UART Module Features | |||
|---|---|---|---|
| Product Name | USB to quad UART module | ||
| Model | FIT-USB-TO-4-UARTS | ||
| Working Temp | -40℃~+85℃ | ||
| SPec. | can support four 5-wire serial port | ||
| Chipset | XR21V1414 | ||
| Main function | XR21V1414(V1414)is an enhanced convert chip to convert USB to 4-ch UART. It can completely 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 function which simplified RS485 application. XR21V1414 working voltage ranges from 2.97V to 3.63V, 5V withstand input, and it is TQFP-48 package | ||
