[MAX10] Instable dual supply VCCA: consequences?

Hi all, We have a board designed with a MAX10 (10M16) with dual supply. Due to a regulator error, the stable 2,5V that was to be fed to VCCA# pins is a "not so stable" (still to be estimated) 3,...

Hello,

I believe you are referring to the same thing. Please refer to page 30 of the same document for more information about VCCIO Range Considerations.

Thanks

Hello,

My understanding is that VCCIO pins are the ones powering the CPLD's IO banks, while the VCCA pins are dedicated to PLL analog block.

I got this from https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/max-10/pcg-01018.pdf page 16 and https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max-10/m10_datasheet.pdf page 7.

The latter also mentions the absolute maximum ratings I mentioned in my first message on pages 4&5.

Thanks

    Hello,

    Sorry for the confusion. Yes you are correct. As stated in the document, conditions outside the range listed in the absolute maximum ratings tables may cause permanent damage to the device. Device operation at the absolute maximum ratings for extended periods of time may have adverse effects on the device.

    Thank you
