Hi team,

I have some sample devices of TPS40210, and I believe they are from 2017 or earlier batches.

Could you help to confirm the marking "7A" meaning?

Does it mean manufactured in 2017, and "A" means it's manufactured in October?

Thanks,

Frank

Hi Frank,

Thanks for using the e2e forum.
You are correct, this unit should be from October 2017.
This means this is still the old material before the process change rework which started ramping in ~2021.

Best regards,
Niklas
