Hi to all,
here is an appnote with the recommended circuitry on page 9. SCL_x and SDA_x are pulled up to 1.8V and both connected to an MCU which has a supply voltage of 3V. If I'm not wrong this MCU's pins will be around 3V when log=high.
However, in the datasheet of this chip, the maximum voltage on the I2C pins are VDD_IO (page 16) which is rated 1.8V at page 13.
Now I'm confused: is the appnote wrong? Any tips would be highly appreciated.
