TM4C1290NCZAD: TM4C1290NCZAD deep sleep mode current consumption

Hi team,

I'm analog FAE supporting some industrial customers in Japan.

My customer has been using TM4C1290NCZAD and provided some question.

He is trying to use TM4C1290NCZAD in deep sleep mode.

However it still has 13mA current consumption under CLK:30kHz and unused peripherals are OFF.

It should be larger than shown in datasheet Table26-55 page 1640.

1. Would it be possible to provide lowest current consumption setting/sequence?
2. Is there anything should be cared for setting deep sleep mode?

I'm looking forward to hearing back from you.

Best regards,

Shota Mago
