Notes:
1.
Currents are additive. For example, where
I
BAT
is specified and the mode is not mutually exclusive, enabling the
functions increases supply current by the specified amount.
2.
I
ncludes all peripherals that cannot have clocks gated in the Clock Control module.
3.
Includes LDO and PLL0OSC (>20 MHz) or LPOSC0 (<20 MHz) supply current.
4.
Internal Digital and Memory LDOs scaled to optimal output voltage.
5.
Flash AHB clock turned off.
6.
Running from internal LFO, Includes LFO supply current.
7.
LCD0 current does not include switching currents for external load.
8.
IDAC output current not included.
9.
Does not include LC tank circuit.
10.
Does not include digital drive current or pullup current for active port I/O. Unloaded I
VIO
is included in all I
