Hi all,

I''d like to have a clarification about the pins RSRVD2 and RSRVD3 of Atlas.
In the new silicon revisions, they are used to configure switching regulator mode (single/parallel) however in the schematics they are left open, so it seems these schematics are not correct for new silicon revisions. Am I right?


Thanks in advance.

llaa57,

The best answer I can give you currently is you "may" be right. We are aware of this discrepancy and have talked with Freescale concerning this. If you are using one of our modules in your design then you should be immune to the issue because we will address it on the module. The definition of those 2 pins not only may be dependent on Atlas silicon revision it is also possible that all Atlas SI revisions will not be available to catalog customers therefore your best bet is to contact Freescale directly, specifically the Atlas group, for clarification on the definition of those pins and what version of SI will be available to you. Hope this helps.
