Description

The PL2303SA is designed primarily for embedded solutions or other solutions where PCB space is limited and lower power consumption is required. Its small footprint allow it to fit in tight spaces. Its very low power consumption, in either operating or suspend mode, make it ideal for bus-power operation, with plenty of power left for attached devices.

PL2303SA provides a convenient simple solution for connecting an RS232-like full-duplex asynchronous serial device (TX-RX only) to any Universal Serial Bus (USB) capable host. PL2303SA highly compatible drivers 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. Flexible signal level requirement on the RS232-like serial port side also allows PL2303SA to connect directly to any 3.3V~1.8V range devices.
