PL2303RA
USB to Serial Bridge Controller (Built-in RS232 Transceiver)
OVERVIEW
The PL2303RA is a low cost and high performance USB-to-Serial Bridge Controller with built-in RS232
transceiver. The PL2303RA provides a convenient solution for connecting an RS-232 full-duplex
asynchronous serial device to any Universal Serial Bus (USB) capable host. The PL2303RA 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 PL2303RA 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, PL2303RA
operates at very low power consumption with guaranteed data rate up to 1000kbps.
