    I’m not actually impressed by the power.

    Normal run: 1.08 mA at 7.3728 MHz

    I’ve… seen better.

    • Voltage range – 1.8V to 5.5V
    • On-board LDO

    Oh… well… that’s cool. 5.5V and 1.08mA is actually impressive, assuming the 1.08mA is measured at this higher voltage.

    A lot of the lower-power uCs need buck-converters to drop down to 1.8V requiring an external inductor. This suggests 1.08mA at 5.5V (not that I’ve read the datasheet yet, but… a more realistic low-cost design). Inductors / buck converter is necessary for the absolutely lowest power usage
