2. CPU executing typical data processing
3. The run from RAM consumption can be approximated with the linear formula:
I
DD
(run_from_RAM) = Freq * 90 µA/MHz + 380 µA
4. Oscillator bypassed (HSEBYP = 1 in CLK_ECKCR). When configured for external crystal, the HSE consumption
(I
DD HSE
) must be added. Refer to Table 28.
