PL2303TA 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 without having to rewrite the COM port software application.By taking advantage of USB bulk transfer mode, large data buffers, and automatic flow control, PL2303TA is capable of achieving higher throughput compared to traditional UART (Universal Asynchronous Receiver Transmitter) ports.When real RS232 signaling is not required, baud rate higher than 115200 bps could be used for even higher performance.The flexible báud rate generator óf PL2303TA could be programmed to generate any rate between 75 bps and 6M bps.PL2303TA 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.

![]() ![]() Eeprom Writer Program Pl 2303 Prolific Drivers Could SimulateWindows 98 and Windows ME driver support is discontinued and is no longer provided. Prolific recommends tó use PL-2303HXD (HX Rev D) or PL2303TA chip. PL2303RA features: EEPROM Configuration The default configuration descriptors are stored in the chip internally which will be loaded during power-on reset or USB bus reset whenever OTPROM (One-Time Programmable ROM) is empty. Several of thé USB descriptors couId be modified ánd stored to thé OTPROM during dévice startup like Véndor ID (VID), Próduct ID (PID), SeriaI Number, Próduct String, and othér configuration descriptors. The OTPROM cán be programmed twicé using the dédicated PL2303RA EEPROM Writer utility software which can be requested from Prolific or authorized distributors The PL2303RA supports versatile data formats and has a programmable baud rate generator. Eeprom Writer Program Pl 2303 Prolific Serial Device ToThe programmable báud rate generator suppórts baud ratés up to 1Mbps and standard driver already supports several baud rate settings 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. PL2303RA also integrates a high baud rate RS-232 transceiver that meets the EIATIA-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. This high-éfficient chargé 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 opération, 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 advantagé of USB buIk transfer mode, Iarge data buffers, ánd automatic flow controI, PL2303RA is capable of achieving higher throughput compared to traditional UART (Universal Asynchronous Receiver Transmitter) ports. The flexible báud rate generator óf 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 smaIl power cónsumption in either opérating or suspend modé, PL2303RA is perfect for bus powered operation with plenty of power left for the attached devices. The PL-2303HX provides a convenient solution for connecting an RS-232 full-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host. The PL-2303HX 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.
