I believe you have got one to (or more) somewhat slow otherwise below rated supplies
I am currently coping with Max10M16DAF256 and that i have a problem with the brand new ADC. sof file it works great. pof document the new ADC can not work more, we.age ADC info is always zero, due to the fact someone else portion works truthfully.
When using
We have also seen whenever coding with .pof document nonetheless allow the suppy voltage towards the, the newest ADC works. However, once reset the supply current (turn fully off as well as on again), it doesn’t performs more.
In the event the latter then you will want to confirm check the manner in which you launch new ADC Internet protocol address out of reset. Hold it when you look at the reset ‘a absolutely nothing longer’ following the power up. Disappointed this might voice a tiny obscure. It is apparently a consistent question with the forum you to definitely cannot seem to have gotten an obvious, reputable solution.
Should this be your own board you will need to test these and make certain the latest rails rise monotonically. There are no sequencing criteria however, if the try not to go up rightly – maybe not conference new Tramp date – the system tend to misbehave. Consider ‘Figure step 3. Tracked Strength Provides Ramp Up’ on ‘ fuel management member publication (
I additionally found a similar issue with Max10 ADC in another bond, but as if you told you there is no solution for this.
The fresh panel is the worry about design board. The issue is a large number of our boards will work okay which have ” .pof “-file, and several of them understand this ADC situation. To the chat rooms having ADC state, i examined from the equipment of these chatrooms but unfortunately we didn’t find any problem for the apparatus. Such as for example in the above list, the brand new boards are working having ” .sof ” and even ” .pof “-file when the likewise have current is definitely into. Following have voltage was reset, the fresh new ADC do not functions while the rest remains functioning correctly.
This will make me believe a lot more this problem could be electricity associated. You’re certainly to the side of regardless of the issue is given you’ve got functioning chatrooms.
Do you take a non performing board, disconnect the power supplies and you will stamina it of counter provides? My personal issue is that a significantly less than ranked rail actually around giving the inrush required and you can dips causing the POR circuitry a great state, and that (perhaps) actually documented.

You are proper. I did so particular analysis from the energy supplies having Max10, plus it seems like our very own analogue likewise have requires some enough time up to they is at full current peak (the audience is using Max10 twin also provide unit, and that means a couple of electronic provides and you may step 1 analog supply).
As with Max10 Electricity administration user book, it looks like precisely the past power supply for Max10 matter (connected image), therefore we made an effort to swtich for the analogue also have very first and you can expect they to reach maximum peak, following turn on additional a couple digital offers, and this need only couple hundred µs to-arrive max height. This will help to the fresh new maybe not-working ADC in order to become functioning sporatically (not necessarily performing).
Nevertheless when we grab an operating panel (ADC usually really works) and you can perform the contrary succession (i.elizabeth let a couple digital provides for the first, then analogue have), the fresh ADC is still doing work (we expected which should not functions anymore).
Therefore somehow the ADC condition makes reference to the advantage also provide sequence in addition to ramp time of strength provides, however, a definite need for this problem could have been maybe not discovered yet ,.
