I've come to my first battery-powered device with Nordic RF modules.
I'm using a 18F2620 PIC, which reaches some 50-10uA when in sleep (it's good enough, probably I still have to check for something... I'm using internal oscillator, disabled BOR, PWRTE, WATCHDOG and other fancy things...)
But the TRW24 module, even if CE-disabled, still seems to draw some 350-400uA. I'm wondering "how" do I have to set all of its pins (CLK, CS... DATA? will it be floating so I have to keep it low, or high...? and DR?) in order to reduce consumption.
Thank you for your input. I did not find this in the datasheet...
Supposed current drawing in PowerDown mode should be 12uA, if I'm not wrong from the datasheet...
