Introduction

AI Translation

CH382 is a PCI- Express bus converter chip, which converts PCIE bus to dual serial ports and printer port, including two asynchronous serial ports compatible with 16C550 or 16C750, and one EPP/ECP enhanced bidirectional parallel port. The asynchronous serial port provides a transceiver with independent 256- byte FIFO buffer, supports communication baud rate up to 8Mbps and can be used for RS232 serial port expansion of PCIE bus, PCIE high- speed serial port with automatic hardware flow control, serial ports networking, RS485 communication, parallel/printer port expansion, etc.

Features

AI Translation
  • The same chip can be configured as a dual- channel serial ports, single parallel port/printer port, dual serial ports and parallel port/printer port of PCIE bus.
  • Provides two- wire serial host interface, and EEPROM device similar to 24C0X which can be connected to store non- volatile data.
  • The device identification (Vendor ID, Device ID, Class Code, etc.) of the PCIE board can be set in the EEPROM device.
  • Drivers support Windows 98/ME/NT4.0/2000/XP/Vista/7/8/8.1/10/SERVER 2003/2008/2012/2016/2019 and Linux.
  • 3.3V power supply, I/O pins supports 5V withstand voltage, serial ports support low- power sleep mode.
  • The chip function is equivalent to CH367 with CH438, providing 4 serial ports, 8 serial ports and more serial applications.
  • Supports PCMCIA ExpressCard notebook card.
  • 2 fully independent asynchronous serial ports, compatible with 16C550, 16C552, 16C554 and 16C750 and enhanced.
  • Supports 5, 6, 7 or 8 data bits and 1 or 2 stop bits. Supports odd, even, mark, space and no parity.
  • Programmable communication baud rate, supports communication baud rate of 115200bps and up to 8Mbps.
  • Internal 256- byte FIFO buffer, supports four FIFO trigger levels.
  • Supports MODEM interface signals CTS, DSR, RI, DCD, DTR and RTS, which can be converted to RS232 signals.
  • Supports automatic handshake and automatic transmission rate control of hardware flow control signals CTS and RTS, compatible with TL16C550C.
  • Supports serial port frame error detection and Break line interval detection.
  • Supports full- duplex and half- duplex UART communication.
  • Supports SPP, Nibble, Byte, PS/2, EPP, ECP and other IEEE1284 parallel port/printer port working modes.
  • Supports bidirectional- data transmission and a transmission speed of up to 1M byte/s.
