How do i interpret things written on my nrf52832 chip?

[Blue_Jack]

I have a nrf52832 EK with chip encrypted with "N52832-QFAAAA-1509AA". what does all these mean specifically?

[bjorn-spockeli]

All chips in the nRF52 series are marked in the following way

N52XXX
PPVVHP 
YYWWLL

where

• XXX - Part code
• PP - Package variant
• VV - Function variant
• HP - Build code
• YY - Year Code
• WW - Assembly Week
• LL - Wafer Lot Code

So a chip with the following marking

N52832   
QFAAAA 
1509AA 

means that it is a nRF5832 chip in QF package and variant AA. Produced in week 9 in 2015 and is a part of wafer lot AA.

This is shown in section 49 in the nRF52832 Objective Product Specification, found here.
