高速USB HUB控制器芯片,高速USB转8串口芯片,CH348,CH334 高速USB HUB控制器芯片,高速USB转8串口芯片,CH348,CH334 高速USB HUB控制器芯片,高速USB转8串口芯片,CH348,CH334 高速USB HUB控制器芯片,高速USB转8串口芯片,CH348,CH334

沁恒推出采用4端口高速USB HUB控制器芯片CH334高速USB转8串口芯片CH348,可实现USB转32路高速串口。相较于传统方式,通过多级HUB级联多个CH340实现的USB转多串口方案,可节省多个HUB芯片与产品体积,且CH348的每个串口在通讯速度、通讯电压范围等各项指标上较CH340均有增强。CH348芯片的8个串口支持I/O独立供电和硬件流控,支持多路串口同时在最高6Mbps通讯波特率下持续稳定传输,支Windows/Linux/Android/macOS等操作系统,可应用于工控主机、串口服务器、安卓嵌入式主板串口扩展、调试下载、高速串口数据记录等。


应用框图

CH334:4端口USB HUB控制器芯片,HUB——集线器,用于host和device之间USB接口扩展的一个USB设备。 CH334可扩展4个USB设备端口,上行端口支持USB2.0高速和全速,下行端口支持USB2.0高速480Mbps、全速12 Mbps和低速1.5Mbps。除CH348Q外,CH334还可连接其他USB设备,可实现多路串口+“U盘”+“分析仪”等多设备组合的方案。
CH348:USB转8串口芯片,每个UART均内置独立的收发FIFO,发送FIFO为1K字节,接收FIFO为2K字节。串口波特率支持6Mbps,串口IO电压支持3.3V/2.5/1.8V等。提供最多48路GPIO,以及RS485收发控制功能。


接线说明

将CH334上行端口与PC连接;

4个CH348Q芯片分别与CH334的四个下行端口相连。
