1. Add 1 μA to the current value if the device is used in Low voltage mode.
2. This number includes the current used by the automated power and clock management system.
3. For details on 1 MHz mode, see
Section 4.2 “Timer/counters (TIMER)” on page 32.
4. FDCDC will vary depending on VDD and internal radio current consumption (IDD). Please refer to the nRF51 Series Refer-
ence Manual, v3.0 or later, for a method to calculate IDD,DCDC. See Figure 11 on page 50 for a DC/DC conversion factor
chart.
