Hi
I'm looking at the CFAX12864A-WFH or CFAX12864AP1-NFH displays with the Samsung KS0713 controller.
My question is about the static display current consumption (i.e. displaying an image, but no screen updating).
The KS0713 datasheet shows around 70uA typical when using the charge pump, but the LCD datasheets show 1.5mA or 1mA typical rated at 5V only. I find it hard to believe the static LCD image and extra voltage would add this much.
I will be using the internal charge pump and a single 3V or 3.3V supply.
Does anyone know the actual typical operating current of these displays at around 3V?
If it is actually 1mA or so then I've blown my power budget, as I'm targeting around several hundred uA tops.
Thanks
Dave.
