Hi,

We are using CYPD3120 in one of our design. The datasheet mentions voltage range of VDDIO as 1.71 to 5.5.

Can I provide 1.8V to VDDIO pin and effectively make the GPIO(and the Pin Muxed I2Cs) functional at 1.8 Voltage.

My Application processor works at 1.8V and my thought is to avoid using a level translator.

Thanks and regards,

Abhilash G

Hi Abhilash G,

Your thought is correct, you can provide 1.8V to VDDIO.
