The PL-2303 chip provides a convenient solution for connecting a UART-like full-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host. The PL-2303 highly compatible drivers could successfully simulate generic COM ports on most operating systems.
By taking advantage of USB Bulk Transfer Mode, large data buffers, and automatic flow control, The PL-2303 is capable of achieving higher throughput. When real RS232 signaling is not required, baud rate higher than 115200 bps could be used for even higher performance. The flexible baud rate generator of PL-2303 could be programmed to generate any rate between 75 bps to 12M bps.
PL-2303 is exclusively designed for mobile and embedded solutions in mind, providing a small footprint that could easily fit into any small PCB layouts. With very small power consumption in either operating or suspend mode.
