- On-board 3.3V power chip
- Support 8-channel serial port high-speed communication
-
CH348 key features specifications:
- High-speed USB device interface
- Hardware full-duplex serial port, integrated independent transmit-receive buffer
- Baud rate varies from 1200bps to 6Mbps.
- The serial ports support 8 data bits, odd, even, and none parity, 1/2 stop bit.
- Each serial port comes with a 2048-byte receiving FIFO and a 1024-byte transmitting FIFO.
- Signals RTS, DTR, DCD, RI, DSR, and CTS supported for hardware flow control
- The MODEM interface signal pins and 485 transmit and receive control pins:
- CH348Q contains 4 groups of CTS0~3/RTS0~3, and TNOW0-3 (DTR0-3).
- CH348L contains 8 groups of CTS0-7/RTS0-7, DSR0-7, DCD0-7, RI0-7, and DTR0~7 (TNOW0-7).
- Supports half-duplex, status TNOW, used for controlling RS485 to transmit-receive switch.
- Up to 48-channel GPIO input and output.
- Supports RS232/RS485/RS422 interface, through external voltage conversion chip.
- Serial I/Os of CH348L are power supply independently via VIO pins with support for 3.3V, 2.5V, 1.8V
- Built-in EEPROM used to configure the chip of VID, PID, maximum current value, vendor and product information string, etc.
- Operating voltage – 3.3V.
