PL2303TA.HXD.RA.EA.SA停产通知:到2019年底,将淘汰(EOL)全速USB转串行桥控制器的五个高产旧版本。可以用新PL2303G系列产品代替它。请最后一次订购时间为2020年6月。最后一次发货将在2020年末安排。 PL2303GC是一款低成本,高性能的USB至串行桥控制器。 PL2303GC提供了一种方便的小型解决方案,用于将类似RS232的全双工异步串行设备连接到任何USB主机。 Prolific提供了高度兼容的驱动程序,该驱动程序可以在大多数操作系统上模拟传统的COM端口,从而允许基于COM端口的现有应用程序轻松迁移并准备好使用USB。 与传统的UART(通用异步接收器发送器)端口相比,PL2303GC通过利用USB批量传输模式和大数据缓冲区,能够实现更高的吞吐量。 PL2303GC的灵活波特率发生器也可以编程为生成1 bps至12 Mbps之间的任何速率。
