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)是一款增强型的接口转换芯片,由USB接口转换成4通道的UART接口。USB接口完全兼容全速USB 2.0规范并支持12Mbps的USB数据传输速率。USB接口还支持USB挂起、恢复和远程唤醒操作。XR21V1414工作在48MHz的内部时钟,因此不需要外部晶振。内置独立波特率发生器,使用48MHz的内部时钟,能准确地产生任何波特率。 XR21V1414具有128字节发送FIFO和384字节接收FIFO,有助于优化各种应用中的整体数据吞吐量,减少CPU的资源。自动收发方向控制功能, 从硬件和软件方面上简化了的半双工RS-485应用。在多点(9位)模式下自动半双工收发器控制功能简化了典型的多点RS-485接口的应用。 XR21V1414工作电压为2.97V~3.63V,5V的耐压输入,提供TQFP-48封装。
Compatible with USB 2.0
