Can the MAX10 VCCIO supply be set at 2.7V?

I am looking to use the 10M02SCM153I7G which has a single supply (3V3). The system it interfaces with is running at 2V7. I noticed from the datasheet (Table 6) that the recommended power supplies for...

Hi Alex,

I have also spoken with Altera. They did not recommend doing this. The engineer expressed concerns with the bus-hold trip-point technology in the MAX10. I can't really take the risk.

I have since calculated the 2.7V flash device with a 3.0V MAX 10 bank voltage are compatible. I already have a dedicated regulator for the MAX 10 so I will change it from 3.3V to 3.0V. I have other devices connected to the MAX 10 running interfaces at 3.3V, so I will adjust the bank voltages accordingly.

Thanks again for your input.
