PL2303GT USB to RS232 Serial Bridge Controller (Built in RS232 XCVR)
The PL2303GT is a low cost and high performance USB-to-RS232 Bridge Controller with built-in RS232 transceiver. The PL2303GT provides a convenient solution for connecting an RS-232 full-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host. The PL2303GT highly compatible drivers 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.
The PL2303GT integrates a high baud rate RS-232 transceiver that meets the EIA/TIA-232F and CCITT V.28 communications interface specifications. The RS-232 transceiver is a 3-transmitters and 5-receivers device with a high-efficient charge pump circuit embedded. It provides the bipolar output to the transmitters, and makes the transmitters to deliver the RS-232 output voltage levels. Under normal operation, PL2303GT operates at very low power consumption with guaranteed data rate up to 1Mbps.
