PL2303GE USB to Full UART IC With Integrated System-Level ESD Protection

The new PL2303GE chip is the latest G-Series IC product added to the popular PL2303 USB to Serial (UART) Bridge Controller family, replacing the PL2303EA (with ESD protection) chip. It provides an advanced full-featured single-chip bridge solution for connecting a full-duplex UART asynchronous serial interface device to any Universal Serial Bus (USB) capable host. The PL2303GE provides robust USB drivers to simulate the traditional COM port (via virtual COM Port) on most operating systems, allowing existing serial UART applications based on legacy COM ports to easily migrate and be made USB-ready.

Description

The new PL2303GE chip is the latest G-Series IC product added to the popular PL2303 USB to Serial (UART) Bridge Controller family, replacing the PL2303EA (with ESD protection) chip. It provides an advanced full-featured single-chip bridge solution for connecting a full-duplex UART asynchronous serial interface device to any Universal Serial Bus (USB) capable host. The PL2303GE provides robust USB drivers to simulate the traditional COM port (via virtual COM Port) on most operating systems, allowing existing serial UART applications based on legacy COM ports to easily migrate and be made USB-ready.
The PL2303GE provides USB port system-level ESD (electrostatic discharge) protection that eliminates the need for external ESD protection components to minimize PCB size and save BOM costs. The PL2303GE offers ESD protection on the USB port pins up to ±15kV Human Body Model (HBM) and meets the IEC-61000-4-2ESD specification.
The new PL2303GE is pin-to-pin compatible with the PL2303EA chip. It also integrates an internal precise clock generator (no external crystal required), USB 1.1 transceiver, Serial Interface Engine (SIE), LDO voltage regulator, power-on-reset (POR), FIFO data buffers, and OTPROM.
