Hi,
We fond disagreement between the "Hardware Development Guide for the MIMXRT1050/MIMXRT1060 Applications Processor, Rev.3" and the "MIMXRT1060-EVK" schematics, that we use as reference, on the decoupling caps required. This might be a minor issue, but we like to have this clear. There is two distinct disagreements:
VDD_SNVS_CAP
For this power rail, table 2 of the Hardware Development Guide recomend the following:
So tow caps, one 220nF and one 4.7uF, fine. Here is the EVK schematics:
Only 220nF. Here the EVK does not follow the recommendation for the Hardware Development Guide. Is that fine or should we stick to the recommendation ?
DCDC-LP
Here the Hardware Development Guide says:
The EVK schematics shows:
Is the C37 required ? Also, there is also a lot of decoupling caps on VDD_SOC_IN that would count in the 33uF as the Hardware Development guide says. Should we lower C36 value?
What should we follow on those two cases ? EVK schematics of Hardware Development Guide ?
Hello,
Hardware Development Guide is the reference for the customer. EVK schematics is confirmed by our expert team. You may refer to the Hardware Development Guide and follow the EVK schematics.
