I currently design a product that needs to be battery powered and its just not possible in the same way on the 2040 as esp32 with the ULP and the deep sleep current.

I also happen to be working on an ultra-low power project with an ESP32. It is hard to beat that 5uA deep-sleep current!

  Try <1µA/MHz active current consumption on the Ambiq Apollo4 chips.

    Thanks for that, looks interesting. One note, their website [1] claims 5uA/MHz, not 1 [1] https://ambiq.com/apollo4/ https://ambiq.com/apollo4/

      Yes, that's correct. I had confused it with the total consumption at rated speed - ~1mA and mixed up my figures.
