MAX 10 Power-Up

Hi everybody.

I need the power-up characteristics of the MAX 10. For example, at the MAX II documentation there is the figure attached in which the conditions, to keep the 'user mode' on, are obvious.

I would like to know what is the Power On Reset trip level on MAX 10? Once at the user mode, in what voltage level the pins come back to tri-state mode?

I hope someone can help me.

Regards,

Ronan.

    As far I know Altera never publish any device POR trip point voltage level. There is no specific voltage level for tristate pins. Typically tristate pins are high z where it can have either an internal weak pull up or weak pull down settings. Thus if you scope the pins, you might see voltage level is near to high or low level due to the internal weak pull up or pull down resistor.
