Honored ContributorMAXV maximum current per bank
Hi,
What's the maximum current per bank in 5M570ZT144C? I need to drive 56 leds with 5mA (280mA). Is it possible? VDDIO = 3V3 Thanks. Bruno BernardiForum Discussion

Altera_ForumThere's no explicite specification in the datasheet, but I think you can refer to the MAX II related specification in AN286.

AN286:"Although a single pin from a MAX 7000B device can sink up to 50 mA of DC current, each GNDIO group can concurrently sink up to 200 mA" Does not exist similar specification for MAXV family?

If 170mA per pin. Would be 850mA per bank? according to AN286: "For example, the EPM240 device has six GNDIO pads, which provide six I/O regions that can sink up to 130 mΑ. If you need to sink 15 mA for the outputs, you can have eight outputs per region. With the six regions of I/O between GNDIO pads, there are 48 possible outputs, each sinking 15 mA."

I think it's pretty clear if you review the MAX II data sheet and pin-out lists. I assume that MAX V has about the same current capability, but your requirements are distinctly below the discussed maximum ratings.
