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.

no ram,it will be 1.4uA not 0.4uA

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

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.
