Product Introduction: CH343 is a USB bus adapter chip that enables USB to high-speed asynchronous serial port conversion. It also supports automatic recognition and dynamic adaptation of communication baud rates of 115200bps and below. It provides commonly used MODEM communication signals for expanding asynchronous serial ports for computers, or upgrading ordinary serial devices or MCUs directly to the USB bus.

Performance characteristics: Full speed TYPE-C USB device interface, compatible with USB V2.0. Built in firmware, simulating standard serial ports, used to upgrade original serial peripheral devices, or adding additional serial ports through USB. The serial application program on the computer side under the Windows operating system is fully compatible and does not require modification. Supports built-in CDC class drivers or multi-functional and high-speed VCP vendor drivers for non installation operating systems. Hardware full duplex serial port, built-in independent transmit and receive buffer, supporting communication baud rates of 50bps~6Mbps. Optional automatic recognition and dynamic adaptation at commonly used communication baud rates of 115200bps and below. The serial port supports 5, 6, 7, or 8 data bits, and supports odd parity, checksum, blank, flag, and no checksum. Support commonly used MODEM communication signals RTS, DTR, DCD, RI, DSR, CTS. Support CTS and RTS hardware automatic flow control. Supports half duplex and provides sending status TNOW support for RS485 switching. By adding a voltage converter device, it supports RS232 interface. The USB port supports 5V power supply voltage and 3.3V power supply voltage. 1/0 independent power supply for serial port, supporting 5V, 3.3V, 2.5V, and 1.8V power supply voltages. Built in power on reset, built-in clock, no need for external crystal oscillator. The CH343P has a built-in EEPROM, which can configure chip parameters such as VID, PID, and maximum current value. The chip is equipped with a Unique lD (USB Serial Number). Provide SOP16, ESSOP10, and OFN16 lead-free packaging, compatible with ROHS. Size: 35 * 13mm
