Note 1. The values are guaranteed by design.
Note 2. LDO and Leak are internal voltage regulator’s current and MCU’s leakage current. It is selected according to the temperature of Ta.
Note 3. Δ(Tj-Ta) = 20 °C is considered to measure the current.
Note 4. To determine the current consumption per channel, group or unit, divide Current [mA] by the number of channels, groups or units.
Note 5. Includes current for 1 channel of SCI.
Note 6. RTC operationg current flow into VRTC power supply.
