As a Host/Master host, it supports common synchronous serial interfaces such as 2-wire and 4-wire.FlexWireTM technology, enables flexible 2-wire to 5-wire synchronous serial ports through software.Which is similar to the memory read/write mode. The MEM mode provides signals such as A0, RD# and WR# etc.EPP provides signals such as AS#, DS# and WR# etc.Two modes are available: EPP mode and MEM mode.Supports two-way communication of the IEEE-1284 specification and supports one-way and two-way transmission of printers.Supports various standard print port printers, optional low speed printing and high speed printing.Compatible with Windows/Linux/MACOS and so on, and the application is fully compatible.Standard USB print port for upgrading the original print port printer, compatible with the relevant USB specifications.Supports access to the CH341 external serial EEPROM memory in UART communication.through external voltage conversion chip. Provides further RS232, RS485, RS422 interface, etc.Supports UART transmit enable, UART receive ready rate control signals and so on, and common MODEM interface signals.Supports 5, 6, 7 or 8 data bits and 1 or 2 stop bits, supports odd, even, none, mark, space parity.

Emulate standard UART interface, used to upgrade the original serial devices or expand additional UART via USB.Only compatible with the applications, and cannot be absolutely the same.RoHS compliant SOP-28, SSOP-20 and QFN28 lead-free package.Low cost, convert the original serial port peripheral devices, the original print port printer, and the original parallel port peripheral devices to USB directly.Optional: customize the vendor ID, product ID, serial number, etc.Full speed USB device interface, USB 2.0 compatible.In addition, CH341B/F/A support commonly used synchronous serial interfaces such as 2-wire interface (SCL line, SDA line) and 4-wire interface (CS line, SCK/CLK line, MISO/SDI/DIN Line, MOSI/SDO/DOUT line), etc. In parallel port mode, CH341 provides an 8-bit parallel interface in EPP mode or MEM mode for input and output data directly without a microcontroller/DSP/MCU. In LPT mode, CH341 provides a standard USB print port compatible with USB-related specifications and the Windows operating system for upgrading a print port printer directly to the USB. In UART mode, CH341 provides UART transmit enable, UART receive ready rate control signals and so on, and common MODEM interface signals, to expand UART interface of computer or upgrade common serial communication devices to USB directly. CH341 is a USB converter chip, which converts USB to serial UART interface, printer interface, parallel port interface, and common 2/4 synchronize serial communication interfaces etc.
