CH382 is a dual serial port and printer port chip for PCI-Express bus, including two 16C550 or 16C750 compatible asynchronous serial ports and an EPP/ECP enhanced bidirectional parallel port.
The asynchronous serial port provides a 256-byte FIFO buffer with independent transceivers, supports a communication baud rate of up to 8Mbps, and can be used for PCI-E
Bus RS232 serial port expansion, 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 ports, single parallel port/printer port, dual serial ports plus parallel port/printer port of PCI-E bus.
-Provides a two-wire serial host interface, which can be connected to serial EEPROM devices like 24C0X to store non-volatile data.
-You can set the device identification (Vendor ID, Device ID, Class Code, etc.) of the PCIE board in the EEPROM device.
-3.3V power supply voltage, main I/O pins support 5V withstand voltage, and serial port low-power sleep mode.
● Serial port
-Two completely independent asynchronous serial ports, compatible with 16C550, 16C552, 16C554 and 16C750 and have been enhanced.
-Support 5, 6, 7 or 8 data bits and 1 or 2 stop bits.
-Support odd, even, no check, blank 0, mark 1 and other check methods.
-Programmable communication baud rate, support 115200bps and communication baud rate up to 8Mbps.
-Built-in 256-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.
-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.
