WCH CH351Q
PCI Bus dual Serial port or Printer port Controller
Overview
CH351 is a dual serial port or printer port chip for PCI bus. It contains two 16C550-compatible asynchronous serial ports or an EPP/ECP enhanced bidirectional parallel port. The asynchronous serial port supports half-duplex transmission and reception automatic switching, and supports a communication baud rate of up to 4Mbps. RS232 serial port expansion for PCI bus, PCI high-speed serial port with automatic hardware rate control, serial port networking, RS485 communication, parallel port/print port expansion PCI plug-in card, etc.
Features
