LP-MSPM0C1104: MSPM0 sleep current level

Part Number: LP-MSPM0C1104

Tool/software:

Hello,

i attended last year the Embedded World tradeshow. At Ti booth, i noticed the MSPM0 MCU from Ti, with claim of sleep current below 50 nA.
I purchased later on the eval kit (LP-MPSM0C1104 lauchpad), while searching information today to test and confirm that sleep current, i can't find anymore that 50 nA value. I am wondering if i purchased the wrong MSPM0 version, can you please point me to the right MCU version offering that performance level?

Thank you

Regards

Julien
