CH382 is a dual serial port and print port chip for PCI-Express bus, including two asynchronous serial ports compatible with 16C550 or 16C750 and one EPP/ECP enhanced bidirectional parallel port.
Asynchronous serial port provides independent 256-byte FIFO buffer for sending and receiving, supports 8Mbps communication baud rate, can be used for RS232 serial port expansion of PCI-E bus, PCI-E high-speed serial port with automatic hardware rate control, serial port networking, RS485 Communication, parallel port/print port expansion, etc.
The same chip can be configured as dual serial port, single parallel port/printing port, dual serial port plus parallel port/printing port of PCI-E bus.
Provides a two-wire serial host interface, which can be connected to a serial EEPROM device similar to 24C0X for storing non-volatile data.
The device identification (Vendor ID, Device ID, Class Code, etc.) of the PCIE board can be set in the EEPROM device.
3.3V power supply voltage, main I/O pins support 5V withstand voltage, and support serial port low-power sleep mode.
●Parallel port
- Support SPP, Nibble, Byte, PS/2, EPP, ECP and other IEEE1284 parallel/printer working modes.
- Support bidirectional data transfer, support up to 1Mbyte/second transfer speed.
●Operating system
- Windows 98SE/ME/NT 4.0/2000/XP/Vista/Server2003/Win 7, Linux
