Power consumption of nRFready Desktop2

[Jeffery]

Hi Could you provide the power current in System on Active, System on Sleep, and System OFF for nRFready Desktop2 keyboard and mouse? nRF51 was programmed Desktop 2 v1.0.4 firmware. Thanks.

Regards, Jeffery

I don't have any specific current consumption numbers for this design, but all the current consumption numbers needed are in the nRF51822 PS. Typically, the current consumption in system on, idle, is ~3-4 µA with the 32 kHz running, and less than 1 µA in system off.

Edit: It should be noted that there is a PAN on these numbers, causing the current consumption to be higher than specified. See PAN-028, item 27. This is fixed in the latest revision of the chip.

hi , i found the current issue more than spc current in PAN doc #27.

no ram,it will be 1.4uA not 0.4uA

Sorry that I forgot to mention this, but you are correct that there is a PAN item on these currents, and on the current chip revision, you may see numbers that are above those in the PS. However, the chip-to-chip variation can be pretty high, so you might also be lucky.

Either way, this should be fixed in the latest revision of the chip.
