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.

• Serial Port

- Two completely independent asynchronous serial ports, compatible with 16C450, 16C550 and 16C552 and enhanced.

- Support 5, 6, 7 or 8 data bits and 1 or 2 stop bits.

- Supports odd, even, no parity, blank 0, mark 1 and other verification methods.

- Programmable communication baud rate, supporting 115200bps and up to 4Mbps communication baud rate.

- Built-in 16-byte FIFO first-in-first-out buffer, supporting 4 FIFO trigger levels.

- Support MODEM modem signals CTS, DSR, RI, DCD, DTR, RTS, which can be converted to RS232 level by 75232 chip.

- Support hardware flow control signals CTS and RTS automatic handshake and automatic transmission rate control,

compatible with TL16C550C.

- Support serial frame error detection and Break line interval detection.

- Supports full-duplex and half-duplex serial communication, provides DTR/TNOW serial port sending status signal,

  supports RS485 receiving and sending automatic switching.


• IEEE1284 Parallel Port

- Support SPP, Nibble, Byte, PS/2, EPP, ECP and other IEEE1284 parallel port/print port working modes.

- Support two-way data transmission, supporting a transmission speed of up to 2M bytes per second.
