PL2303SA   USB to Serial Bridge Controller

The PL2303SA is a low cost and high performance USB-to-Serial Bridge Controller. The PL2303SA provides a convenient small-factor solution for connecting an RS232-like full-duplex asynchronous serial device (TX-RX only) 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 (using TX-RX only) to easily migrate and be made USB ready.

By taking advantage of USB bulk transfer mode and large data buffers, PL2303SA is capable of achieving higher throughput compared to traditional UART (Universal Asynchronous Receiver Transmitter) ports. The flexible baud rate generator of PL2303SA also could be programmed to generate any rate between 75 bps to 115 kbps by driver customization.
