PL2303GE
ESD-Protected USB to Serial Bridge Controller
OVERVIEW
The PL2303GE is a low cost, high performance, and ESD-protected USB-to-Serial Bridge Controller. The PL2303GE provides a convenient solution for connecting an RS-232 full-duplex asynchronous serial device to any Universal Serial Bus (USB) capable host that requires USB port system-level high ESD protection.
The PL2303GE eliminates the need for external ESD protection components to minimize PCB size and save BOM costs. It offers ESD protection on the USB port pins up to ±15kV Human Body Model (HBM) and is according to the IEC-61000-4-2 ESD specification.
The PL2303GE is exclusively designed for mobile, embedded systems, and industrial control systems, providing a stable and flexible solution for connectors and devices. With very small power consumption in either operating or suspend mode, it is perfect for bus powered operation with plenty of power left for the attached devices. Flexible signal level requirement on the RS-232 serial port side also allows the PL2303GE to connect directly to 5V ~ 1.8V devices.
The PL2303GE integrates embedded clock and OTPROM (One-Time Programmable ROM) to save external crystal and EEPROM.

- 🔗🌐 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.
