Several of the PIC models have a low power mode where they run off an internal RC circuit somewhere in the KHz range. Just enough to wake up on an interrupt or some external stimuli and really pushes their power usage way down. For a PIC10KF320/322 you're looking at: Sleep: 20nA, 1.8V Operating: 25uA @ 1Mhz, 1.8V Watchdog Timer: 500nA, 1.8V Of course that's dependent on what' you're doing with the io pins etc. See:http://ww1.microchip.com/downloads/en/DeviceDoc/40001585D.pdf http://ww1.microchip.com/downloads/en/DeviceDoc/40001585D.pd... edit: fix typo

For comparison, TI's MSP432 series is specified at 90 uA/MHz running, 850nA sleep with RTC enabled - and that's a Cortex M4 part with hardware FPU, not even an M0. I think Atmel's newest low-power M0 parts are even more impressive. Plus the Internet of Things means companies are wanting to run increasingly demanding code on low-power embedded devices. 8-bit chips are getting squeezed hard by ARM.
