supply chain management of NRF52840

[4RickK]

Recently our firmware team encountered a new version of NRF52840 and our hardware team "orders the available chip". How can I know and manage the version when we design the device? What are the relevant versions for us to track? Please explain the markings on the chip and what they represent. Can two chips be marked identically and have any different form, fit or function? In this case it was a firmware discrepancy that came to my attention, what else might I need to be looking for?

Best Regards,

Rick Kaim
