Using I2C1 and I2C2 with HSI

Hi,

I am planning to use STM32F030C8 in my design without external  crystal. I will use HSI as clock. Can I use I2C1 (PB8, PB9) and I2C2 (PB10, PB11) with HSI? 

 

Thank you for the help,

Of course you can do that. Unlike UART, I2C has a clock line via which the devices are synchronised.
