Anyone used the 16C924 with a small LCD? 
The data sheet is a bit incomplete in terms of working out the power
consumption. 
What I want to know is what's the lowest possible power consumption
in sleep, lcd on, 3.6v, WDT off, INCLUDING the lcd (small, 40x30mm,
about 30 seg x 2 com). 
I assume the 32K t1 osc is the lowest power, and it can be used to
wake the CPU every sec. or so. In my app, sleep current dominates -
avarage current when awake will add about 1uA (awake 1ms per sec at
4MHz).
The data sheet gives values for LCD voltage generation, but NOT the
LCD module on its own, i.e. with external voltage generation, and
gives no clue about typical power draw of the LCD itself - obviously
this is panel dependent, but a rough guide (e.g. power vs. capacitance
or a couple of specific displays) would have been nice.

Has anyone measured the supply current in a real app ?
I'd like 15-20uA max - anyone know is this realistic ? 
Any suggestions for other CPUs would be welcome - low cost is very
important, but OTP preferred to mask.
