PCI Bus dual Serial port or Printer port Controller
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.
- Fully compliant with PCI Local Bus Specification, Revision 2.2
- Fully customizable PCI Configuration Space
- PCI signaling Supports PCI Power Management
• 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.
