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 seperately.
2) This current includes the E-Ray module power consumption, including the PCP operation component.
3) The I_DD decreases typically by 97 mA if the f_CPU decreases by 50MHz, at constant T_J
4) The I_DD decreases typically by 105 mA if the f_CPU decreases by 50MHz, at constant T_J
5) D-Flash read, write, or erase opoeration in parallel to P-Flash operations name in Test Condition is covered
already in the give current limits.
6) Relevant for the power supply dimensioning, not for thermal considerations.
7) In case of erase of Program Flash PFx, internal flash array loading effects may generate transient current
spikes of up to 15 mA for maximum 5 ms per flash module.
8) For power supply dimensioning of V_DDP 30 mA have to added for flash programming case.
Note: In general current consumption for operations with data flash are always lower
than the defined values for program flash read operation.
5.2.6.1 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
