Excuse the nitpicking: why does the documentation say:

"Dx0. The "x" represents a digit between 0 and 9"

when actual devices (including marketing material die photos) don't follow this scheme, e.g. QIAAD0?

Or is "Dx0" a mistake, and it should instead say "Dx"?

Hi,

[quote user="Johan Sandgren"]N52840 - line 1
QIAAD0 - line 2
2102UH - line 3[/quote]

QI = Package variant code == aQFN

AA = Function variant code == 1024(Flash) & 256 (RAM)

Build code{

D = Hardware revision code

0 = Production configuration code }

2102UH = Tracking code == Year 2021, Week 2, Wafer lot UH

Comparing this with the combability matrix I can see that you have revision 2.

See this part.

I have on top of chip these:
N52840 - line 1
QIAAD0 - line 2
2102UH - line 3

Line 2: "QIAA" matches lots of revisions.
Using also Line 2: "D0" - it does not match either Engineering D or revision 2.
So which one is it I have?

Why isn't your docs usable with what you print on the chips? That's a needed improvement.

Hi,

AAD0 means that you have a revision 2, which can either be a aQFN73 or a WLCSP package.
