I would like to know if there are any microcontroller models with high-speed USB interface, ultra-high-speed I2C 1Mhz or above [Copy link]

Can you please tell me which MCU model has USB interface and super high speed I2C 1Mhz or above?

What does interface mean?

The I2C bus data transmission rate is 100kbit/s in standard mode, 400kbit/s in fast mode, and up to 3.4Mbit/s in high-speed mode.

It is true that not all microcontrollers support high speed

What specific application requires I2C to be so fast?

Direct FPGA can

FPGA is OK, but it needs to be designed separately. I want to find an integrated chip

I2C is used as the burning interface, so the speed will affect the burning time

You can go to the WCH official website to find

STM32H7, G series, and U series can all reach 1M. ESP32 and ESP8266 can reach 800K. Some of Yateli's MCUs can also reach 1M. It seems that many MCUs with slightly better performance have them. . . . So there are many choices. . . .

Thank you for the information

I2C high-speed mode requires a special pulse sequence to enter high-speed mode. If the host software is not well designed, it can only use 400K.

I haven't seen any ARM or MCU that supports ultra-high-speed 3.4Mhz I2C yet, so I'm here to ask for advice.
