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...

Alex, thanks for your rapid reply - really helpful and insightful.

My design uses a level shifter between the MAX10 (single supply at 3V3) and a flash IC running at 2V7. The flash interface is 50MHz (max) 8-bit asynchronous. The get the data to a PC I use an FTDI device from the MAX10. My goal is to make the design as small as possible, and the level shifter is one of the biggest components and hence I want to remove it.

Do you think 50MHz would be fine with a bank voltage of 2V7?

To save space, I am trying not to generate a new voltage - so I could consider powering the bank at 3.0V. I'd have to make sure the logic high qualifies for the fpga and that 3V isn't going to damage the flash device powered at 2.7V or the microcontroller (they share the same bus to the flash).

Thanks again for your insight,

James
