Introduction
USB-HS-Bridge is a CH347T/CH347F development board made by MuseLab, based on WCH CH347T/CH347F MCU. It is equipped with USB 2.0 high-speed device interface (480Mbps bandwidth ) and supports USB to I2C/SPI/UART/JTAG/GPIO, which can be used to debug and download FPGA development boards and debug various peripheral sensors.
Specification
Features
● USB 2.0 high-speed device, 480Mbps bandwidth
● High-speed dual serial ports, which supports up to 9Mbps baudrate.
● USB to I2C ,which can be used to operate EEPROM or various sensors.
● USB to SPI, which supports 2-way chip select signal and can operate 2 SPI slave devices in time division. The highest frequency can be up to 36MHz.
● USB to JTAG, 4-wire standard JTAG protocol, high-speed transmission, the highest frequency can be up to 60MHz.
Working Mode
CH347T
Since CH347T does not have enough pins, DTR1 and RTS1 need to be used to configure the mode when powering up.
CH347F
The package of CH347F is QFN28, which has enough pins, so there is no need to switch the working mode to reuse the pins. UART0/UART1/I2C/SPI/JTAG can be used at the same time. and the IO level is adjustable by switch, the options are 3.3V/2.5V/1.8V/Vref.
