RFM70 Power Down
I am trying to bring the RFM70 into Power Down mode. I do that by setting the Power Up bit (Bit 1) in the CONFIG register (Register 0 in Bank 0) to 0. This does have an effect. I do see power consumption drop. However, it only drops to about 90 µA. That is far more than the 3 µA specified in the data sheet. I measured power consumption on every pin and found that nothing is consumed on any connection with the MC. So it seems that the RFM70 itself is consuming the 90 µA although in Power Down mode.
Has anyone got the RFM70 close to the 3 µA from the data sheet or does anyone know if there is anything needed in addition?
Thanks!
