MAX10 FPGA high power consumption during programming of on-chip flash

During programming (with Quartus Programmer) of the on-chip flash (POF configuration into CFM memory) in MAX10 FPGA (10M16SAU324I7G, single 3.3V power supply), the current consumption on 3.3V jumps f...

Hello,

It depends on Flash power up requirement. MAX10 has 3.3V voltage regulator built-in to convert to other power supplies, like 2.5V etc. The 1.0A might be temporary shoot up for inrush current when MAX10 is power up and internal voltage regulator power kicked in.

Hi Farabi,

The problem is that this higher current lasts very long, for the entire duration of programming of internal flash of MAX10, roughly several seconds. In my understanding this cannot be an inrush current, which would go for , say typically 10ms.

I am also using 10M16SA with smaller pincount, and here I have never see such an increase on power cunsumption during programming. In this case there was almost no increase of power consumption during programming at all.

Regards,

Peter
