Honored ContributorI am using a MAXII EPM240T100I5N device and I want to determine what the power consumption of the device is when it is running in JTAG (boundary-scan) mode when the device is running without any configuration on it. I have checked the device resources thoroughly and there is no indication as to how I would find this out. Does anyone have any ideas where I can find this information?
Honored ContributorMAX II is a SRAM based device, power consumption is mainly caused by switching actions. I think, without JTAG activity, you can expect the standby supply current specified in the datasheet.
Honored ContributorAssuming that in the worst case, all the boundary-scan capable pins were active and driving the output, what kind of power would that draw?
Honored ContributorSolely depend on the output load.
Honored ContributorI understand that it will depend on what load is attached to each pin, but I am trying to establish the worst-case current sourcing to use as a benchmark. In other words, what is the maximum current that each JTAG output can supply assuming a 3.3V output? Is there anywhere that such information is available?
Honored ContributorHonored ContributorYes FvM, that is what I meant. I did not phrase it technically correctly. The information regarding the maximum allowed output current and the shorting is useful and is what I was looking for. Where can I obtain a reference containing such information?
Honored ContributorJust look at the MAX II datasheet, Chapter 5. DC & Switching Characteristic.
Honored ContributorThank you FvM
