Original CH340G/340C/340G/340T/340E IC R3 Board Free USB Cable Serial Chip SOP
Product Information:
CH340/USB bus adapter chip
1. CH340 is a USB bus adapter chip, which can realize USB to serial port or USB to print port.
2. In the serial port mode, CH340 provides common MODEM contact signals, which are used to expand the asynchronous serial port for the computer, or directly upgrade the common serial port device to the USB bus.
Features:
①Full-speed USB device interface, compatible with USB V2.0
②Simulate the standard serial port, which is used to upgrade the original serial port peripheral devices, or to add additional serial ports through USB.
③The serial port application program under the Windows operating system on the computer side is fully compatible and does not need to be modified.
④Hardware full-duplex serial port, built-in transceiver buffer, support communication baud rate 50bps~2Mbps.
⑤Support common MODEM contact signals RTS, DTR, DCD, RI, DSR, CTS.
⑥ Provide RS232, RS485, RS422 and other interfaces by adding level conversion devices.
⑦CH340R chip supports IrDA standard SIR infrared communication, supports baud rate 2400bps to 115200bps.
⑧The software is compatible with CH341, and the driver of CH341 can be used directly.
⑨Support 5V power supply voltage, 3.3V power supply voltage and even 3V power supply voltage.
⑩CH340C, E and CH340B have built-in clock, no need for external crystal oscillator, CH340B also has built-in EEPROM for configuring serial number and so on. Available in S0P-16 and SS0P-20 and MS0P-10 lead-free packages, RoHS compliant.
