RE: nRF54L Power Consumption: sleep and tx power

Hello Cynthia,

Q1: We haven't characterised all combinations of configurations, just a subset of normal use cases. There are results of 256k, 192k and 96k and at 128k you'd be at 2.2uA roughly speaking.

Q2: Yes, the delta between LFXO 3.1uA and LFRC at 3.7uA would be added to the setup.

Q3: Assume you are referring to the radio RX and TX currents. They are established as an average across a set of samples. So you'll find samples with higher and samples with lower current consumption than stated, but across a few, you should see and measure the same average.

These are purely for the radio RX and TX operations. MCU would be on top if that is running while you're doing radio.

All this said, there will be variations across samples, so all currents stated are based on an average found across a set of samples.

Best regards

Asbjørn
