12F683 vs 12F1840

I have some of each of these.  I noticed that the datasheet says that the 12F683 has nanoWatt technology, but the 12F1840 doesn't say that.  But the numbers show that the 12F1840 is at least as good on power as the 12F683.  Do they just not use the "nanoWatt" anymore?

    Hi,
    I think your observations are correct.
    Most new PIC products have "nanowatt" like performance. I guess originally it was to distinguish the XLP products from the previous ones (PIC16Fxx or PIC16Fxxx) ...
    Maybe one area to be careful about is power supply. Some PIC16F1 products have F and LF variants.
    If your system is 3.3V max chose the LF variant as it will exhibit lower currents for BOR and sleep as there is no need to have an internal LDO.
    If you look at the recent PIC16F18313, the low power characteristics of PIC12F1840 seem to be better except for the watchdog.
    The PIC12F1840 however does not have PPS (ability to chose the routing between external pins and internal peripherals
    Regards
