CH343G USB to High-Speed Serial Chip CH343G, SOP-16
Introduction
CH343 is a USB bus converter chip, which converts USB to high-speed serial UART interface, provides common MODEM signal, to expand serial UART interface of computer or upgrade common serial devices or MCU to USB bus directly.
Features
- Full-speed USB device interface, USB 2.0 compatible.
- Built-in firmware, emulate standard UART interface, used to upgrade the original serial peripherals or expand additional serial UART via USB.
- Original serial applications are totally compatible without any modification.
- Support free installation OS which built-in CDC driver or multifunctional high-speed VCP vendor driver.
- Hardware full-duplex serial UART interface, integrated independent transmit-receive buffer, supports communication baud rate varies from 50bps to 6Mbps.
- Support 5, 6, 7 or 8 data bits, supports odd, even, space, mark and no parity.
- Support common MODEM interface signals RTS, DTR, DCD, RI, DSR and CTS.
- Support CTS and RTS hardware automatic flow control.
- Support half-duplex, provides sending status TNOW which support RS485 to switch.
- Support RS232 interface, through external voltage conversion chip.
- Support USB port 5V and 3.3V power supply.
- I/O independent power supply, supports 5V, 3.3V, 2.5V and 1.8V power supply, supports backflow prevention.
- Integrated power-on reset, integrated 12MHz clock, no external crystal required.
- CH343P integrates EEPROM used to configure the chip of VID, PID, maximum current value, vendor and product information string, etc.
- Chip has integrated Unique ID (USB Serial Number).
- RoHS compliant SOP16, ESSOP10 and QFN16 lead-free package.
