AM3517: AM3517AZCNA: need Crypto unit being initialized even not used ?

Part Number: AM3517

Hi champs!

Originaly customer is using  AM3505AZCNA in his application.

Due to delivery issues of this part, we suggested these parts as pin/binare compatible products.

  • AM3505AZCNAC  (Crypto enabled)
  • AM3517AZCNA
  • AM3517AZCNAC (Crypto enabled)

Seems AM3517AZCNAC could be delivered, but customer fears, that crypto unit has to be initialized, even not being used in his AM3505AZCNA binary.

Can you check, if extra SW  is needed or reset state is uncritical for their binary?
