ULPWU & PLVD on 12F635 & 16F684

You're welcome, and good luck. Have a look at this when you have time.

It has several good tips on power savings for battery apps:

And this one too: http://www.ac-limoges.fr/sti_ge/IMG/...C_nanowatt.pdf

Also take a peek in the Electrical Specifications section of the data sheet.

It shows current required for various peripherals, oscillators, etc..

Hello Bruce, can you tell me what is the lowest current consumption you have achieved with 12F635?
The minimum I have is 320uA, using external 4MHz resonator. which I don't know is a lot or reasonable? Thanks

[Bruce]

I've never actually tested current consumption on anything I've done with a 12F635, but if
you post your circuit & code I'm sure someone could help you get it below 320uA if it's
sleeping during the time you're measuring current draw.

Any chance I can send you a PM or email ?
