Occasional ContributorAbout Max10 power connection
I was planning to use 10M02SCE144I7G and proceeded with reference to the Pin Connection Guidelines.
was also using the circuit diagram of "EK-10M08E144" as a reference, but I noticed some differences with the guidelines.
It would be helpful if you could teach me the following points.
1) According to the guidelines, the regulators for VCC_ONE and VCCIO are separate in any single supply configuration example. On the other hand, in the circuit diagram of "EK-10M08E144", although a 0.1Ω resistor is included, VCC_ONE and VCCIO are supplied from the same regulator. Is there any problem with the connection?
2) In the guidelines, "Share" is written in the Regulator Sharing column of VCC_ONE and VCCIO. There is no specific explanation, but is it okay to assume that VCC_ONE and VCCIO can be supplied from the same regulator as long as the voltage used is the same?
We apologize for the inconvenience and appreciate your understanding.
Hi,
According to the Max 10 Power Management User Guide, Chapter 2.1.3,
"For Intel® MAX® 10 single-supply devices, only one power supply is required—3.0 V or 3.3 V to power the core of the FPGA. The same power supply can be used to power the I/O if the same 3.0 V or 3.3 V voltage is required. "
So it is correct that "VCC_ONE and VCCIO can be supplied from the same regulator as long as the voltage used is the same".
Best Regards,
