1) Infineon Power Loop: CPU and PCP running, all peripherals active. The power consumption of each custom
application will most probably be lower than this value, but must be evaluated separately.
2) The IDD decreases for typically 120 mA if the fCPU is decreased for 50 MHz, at constant TJ = 150C, for the
Infineon Max Power Loop.
The dependency in this range is, at constant junction temperature, linear.
3) VDDOSC and VSSOSC are not bonded externally in the BC and BD steps of TC1796. An option for bonding them
in future steps and products is kept open.
4) In case the LVDS pads are disabled, the power consumption pro pair is negligible (less than 1µA).
5) For the calculation of junction to ambient thermal resistance RTJA, see Page 130.
