I've reduced the LPC2148 current consumption during power down to 330 uA.
I got to this level by:
- Making sure my IO pins were not sinking current through their pullups.
- Eliminating all floating inputs.
- Turning off unused peripherals.
- Pulling the USB pins D+ and D- to ground with 100k Ohms each.
Does anyone know how to get below this current level? I'd like
to reach the data sheet spec or even the level described in some of
the NXP app notes. 100uA would be sweet. Any ideas?
Cheers,
David
