Power Dissipation
Power dissipation of the MPC5125 is caused by three different components:
Dissipation of the internal or core digital logic (supplied by VDD)
Dissipation of the analog circuitry (supplied by AVDD_SPLL and AVDD_CPLL)
Dissipation of the IO logic (supplied by VDD_IO_MEM and VDD_IO)
Table 10 details typical measured core and analog power dissipation figures for a range of operating modes. However, the
dissipation due to the switching of the IO pins cannot be given in general, but must be calculated for each application case using
the following formula:
Eqn. 1
where N is the number of output pins switching in a group M, C is the capacitance per pin, VDD_IO is the IO voltage swing, f is
the switching frequency, and PIOint is the power consumed by the unloaded IO stage. The total power consumption of the
MPC5125 device must not exceed this value, which would cause the maximum junction temperature to be exceeded.
Eqn. 2

NOTES:
1 Typical core power is measured at V
DD_core = 1.4 V, TJ = 25 °C.
