The internal power consumption is defined as
P
INT
= V
DDP
× I
DDP
(switching current and leakage current).
The static external power consumption caused by the output drivers is defined as
P
IOSTAT
= Σ((V
DDP
-V
OH
) × I
OH
) + Σ(V
OL
× I
OL
)
The dynamic external power consumption caused by the output drivers (
P
IODYN
) depends
on the capacitive load connected to the respective pins and their switching frequencies.
If the total power dissipation for a given system configuration exceeds the defined limit,
countermeasures must be taken to ensure proper system operation:
• Reduce
V
DDP
, if possible in the system
• Reduce the system frequency
• Reduce the number of output pins
• Reduce the load on active output drivers
