I2C of STM32G491 Series MCU

[MB.13]

Hi, 

We are using STM32G491 Series MCU in our application.

Can all the three I2C lanes can be used either as a master or slave.

Is there any specific pins which supports only as a master or only as a slave.

Warm Regards,

Generally, in the STM32G491 Series MCU, all three I²C peripherals—I2C1, I2C2, and I2C3—can be configured to operate either as master or slave devices. There are no specific pins that are restricted to only master or only slave functionality.

For your specific MCU/package, use STM32CubeMX for pin planning and the data sheet as an authoritative document listing all relevant features in the Inter-integrated circuit interface (I2C) chapter.
