Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1） If VDD_SNVS_IN is directly supplied by a super-cap what are the design guidelines? Real-time counter needs to be preserved in the design.
-- A coin battery is a good choice.
2) Is a Schottky diode still required between VDD_HIGH_IN and VDD_SNVS_IN?
-- Please review the Fig 1.

Have a great day,
