PL2303GC Description

Short technical summary and product information.

The PL2303GC by PROLIFIC is a USB-to-Serial Bridge Controller designed for connecting RS232-like full-duplex asynchronous serial devices to any USB host. It offers a convenient small-factor solution with high performance and low cost.

 

This controller is fully compliant with USB Specification v2.0 (Full-Speed) and features an on-chip USB 1.1 transceiver and a 5V to 3.3V regulator. It supports programmable baud rates from 1 bps to 12 Mbps and includes 1024-byte bi-directional data buffers (768-byte receive/256-byte transmit). The device also has an on-chip 96MHz clock generator and supports OTPROM for USB device descriptors.

 

Available in SSOP28 and UQFN24 packages, the PL2303GC is designed to work with existing PC COM Port software applications, allowing for easy migration of applications to USB readiness. Prolific provides highly compatible drivers that simulate traditional COM ports on most operating systems.

 

Key features include full-duplex transmitter and receiver, support for 5, 6, 7, or 8 data bits, various parity modes (Odd, Even, Mark, Space, None), and 1, 1.5, or 2 stop bits. It also detects parity errors, frame errors, and serial breaks.
