Possibility to avoid configuration power requirements for single-supply MAX10 by using nconfig

Hello,

 

I am currently designing a circuit using 10M04SCE144I7G, and I have a question about the power requirements for configuration.

 

[Question premise]

- VCC_ONE, VCCA, and VCCIO are supplied from the same 3.3V switching regulator.

- According to the "MAX10 Configuration User Guide", the power rise time must be within 10ms.

- The recommended power supply voltage for the 3.3V single power supply MAX10 is 3.135~3.465V (3.3V±5%) for VCC_ONE, VCCA, and VCCIO.

 

(Question 1) Can the power rise time be completely ignored by the reset IC driving nCONFIG low until the power supply voltage reaches a certain value?

(Question 2) If question 1 is possible, what is the appropriate threshold voltage for the reset IC?

 

Regards,
