current consumption of active mode versus system frequency, C version, F version

IAM = IAM[1 MHz] ⋅ fsystem [MHz]

current consumption of active mode versus supply voltage, C version

IAM = IAM[3 V] + 105 ∝A/V ⋅ (VCC±3 V)

current consumption of active mode versus supply voltage, F version

IAM = IAM[3 V] + 120 ∝A/V ⋅ (VCC±3 V)
