1) Infineon Power Loop: CPU and PCP running, all peripherals active. The power consumption of each customer
application will most probably be lower than this value, but must be evaluated separately.
2) For operations including the D-Flash the required current is always lower than the current for non-DFlash
operations.
3) Relevant for the power supply dimensioning, not for thermal considerations.
4) In case of erase of Program Flash PF, internal flash array loading effects may generate transient current spikes
of up to 15 mA for maximum 5 ms per flash module.
5.2.5.1 Calculating the 1.3 V Current Consumption
The current consumption of the 1.3 V rail compose out of two parts:
• Static current consumption
• Dynamic current consumption
The static current consumption is related to the device temperature T_J and the dynamic
current consumption depends of the configured clocking frequencies and the software
application executed. These two parts needs to be added in order to get the rail current
consumption.
