    This is a highly competitive field.

    Compare:
    TI MSP430G2xxx Microchip PIC16LFxxxx
    STOP 0.1μA 0.02μA
    Standby 0.5μA 0.5μA
    @1MHz 230μA @ 2.2V 170μA @ 3V

    I run PICs with coils. It is easily possible to cover all frequencies between 50 Khz and 14 MHz.

    I never saw any test results for the coil currents! Can anyone test this? I don't have the equipment here.

    As it happens just today I attended a seminar for Energy Micro who make a seemingly valid claim to be the lowest powered devices in the world.

    The dev board they gave me even has a real time current monitor that integrates into their IDE so you can measure the current consumption of various routines.

    The peripherals have something called a "reflex bus" where one perif can trigger another, such as a timer triggering an A2D, and the A2D can DMA to memory all while the processor core is sleeping.

    And the core itself has 4 (or 5?) power levels, not just ON and OFF.

    Coils? for oscillator elements? Can you explain?

    Interesting...
