PL2303GC
USB to Serial Bridge Controller
OVERVIEW
The PL2303GC is a low cost and high performance USB-to-Serial Bridge Controller. The PL2303GC provides a convenient small-factor solution for connecting an RS232-like full-duplex asynchronous serial device to any USB host. Prolific provides highly compatible drivers that 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.
By taking advantage of USB bulk transfer mode and large data buffers, PL2303GC is capable of achieving higher throughput compared to traditional UART (Universal Asynchronous Receiver Transmitter) ports. The flexible baud rate generator of PL2303GC also could be programmed to generate any rate between 5 bps to 12 Mbps.
FEATURE

- Odd, Even, Mark, Space, or None parity mode
- 1, 1.5,or 2 stop bits
- Parity error, frame error, and serial break detection
- Programmable baud rate from 5bps to 12Mbps
- Independent power source for serial interface
- Works with existing PC COM Port software applications
- 1024-byte bi-directional data buffers (768-byte receive / 256-byte transmit).
- Supports Windows USB Selective Suspend (Remote Wakeup enabled).
- Supports Windows Modern Standby.
- Supports Windows DCHU (Declarative, Componentized, Hardware Support Apps, Universal).
- 🔗🌐 Custom Product Name & Specified COM Port Technology🌐 🔗
- Patented OEM deployment feature – Taiwan Patent I934369: factory-configure a Specified COM Port number and a clear, product-specific Product String in OTPROM / EEPROM so the product name and COM port can be recognized together.
- Specified COM Port range: supports OEM-specified COM Port numbers from 1 to 65,535.
- Multilingual Product String: supports descriptive product names in multiple languages through the OTP programming tool, helping users distinguish which COM port belongs to which product.
- Clear product-to-port identification: program the intended Product String and Specified COM Port Number during manufacturing so Device Manager can present an easy-to-recognize product name together with its COM number, reducing routine end-user reassignment and manual setup.
- Driver / WHQL advantage: these OTPROM / EEPROM identity settings are designed to work with the Prolific Windows VCP driver without an additional WHQL submission for each configured OEM identity.
