PL2303GS USB to Full UART Bridge Controller
The PL2303GS is a low cost and high performance USB-to-Serial Bridge Controller. The PL2303GS provides a convenient small-factor solution for connecting an RS232-like full-duplex asynchronous serial device to any USB host. Prolific provides highly compatible drivers that could simulate the traditional COM port on most operating systems allowing the existing applications based on COM port to easily migrate and be made USB ready.
By taking advantage of USB bulk transfer mode and large data buffers, PL2303GS is capable of achieving higher throughput compared to traditional UART (Universal Asynchronous Receiver Transmitter) ports. The flexible baud rate generator of PL2303GS also could be programmed to generate any rate between 1 bps to 12 Mbps.
