PL2303RA USB to Serial/UART Bridge Controller (Internal RS232 XCVR)

PL2303RA provides a convenient solution for connecting an RS232 full-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host. Prolific provides highly compatible Virtual COM Port drivers that 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.

Description

PL2303RA also 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 and5-receivers device with a high-efficient charge pump circuit embedded. This high-efficient charge pump circuit with 1uF external capacitors 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. PL2303RA also has an active-low shutdown indicating pin that can serve as a shutdown indicator for special application purposes.

By taking advantage of USB bulk transfer mode, large data buffers, and automatic flow control, PL2303RA is capable of achieving higher throughput compared to traditional UART (Universal Asynchronous Receiver Transmitter) ports. The flexible baud rate generator of PL2303RA could be programmed to generate any rate between 75 bps to 1M bps.

PL2303RA is exclusively designed for mobile and embedded solutions in mind, providing a small footprint that could easily fit in to any connectors and handheld devices. With very small power consumption in either operating or suspend mode, PL2303RA is perfect for bus powered operation with plenty of power left for the attached devices.
