I'm using a Bosch BME680 for application and I have a question concerning power supply:
Is it possible to power VDD and VDDIO to 1.8V from one power source, and having the SPI pin coming from the MCU at 1.2V?
Does your MCU only support 1.2V power supply? How about the ripple of 1.2V power supply?
Yes my MCU has to be powered at 1.2V, according to the datasheet it seems to be ok but I have a doubt about having these two differents voltage levels...
The power supply has ripple more or less, so the power supply voltage will be less than 1.2V. It is not recommended to use it at this time.
Thank you for your answer, I thought about this issue, this is why the voltage supply of the sensor will be 1.8V. But my question is, can I have MOSI/MISO/SCLK set on 1.2V voltage supply without having problems with the 1.8V supply?
