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,
