With a sample size of one, the unique ID section of a SAM S70N19 appears to consist of a 0 byte, then 15 printable ASCII characters. My particular one says "15SPKMW23049056".

 

Is this a format I can depend on?

Hi!

 

Same question here. wink

I guess You are right, I have 7 instances of a SAM S70 but can only access 5 pieces now.
The oldest one (bought in 2015) has the ID: 15SNQPK15037006

The other are bought as one in 2017 and the IDs are:

17S414317007029

17S414317001029

17S414317002028

17S414317004029

 

My guess on the format is the following:

YY MMMMM YY AAA BBB

 

YY = year of production

MMMMM = some manufacturing info encoded (possibly series, date etc.)

AAA = maybe some index inside a series

BBB = ?? who knows wink

 

The IDs seem to consist of only alphanumerical and possibly high case characters. It would be good to know more on this by the datasheet...

 

Bests,

Zoltan

Some examples of SAM4SD32CA: 

14SJNPL13028033

17S6W1801035053

The first is possibly from 2014, the second probably 2017. Definitely no non-printing characters if considered in pairs of bytes except a 00 at the start. In the same lot they always seem to start with the same first 8 digits.

Would be nice to use this as a serial number but it seems there is no documentation of the rules so it could change without notice.
