POWER DISSIPATION
To determine total power dissipation in a specific application,
the following equation should be applied for each output:
C
× V
DD
2
× f
C = load capacitance, f = output switching frequency.
Example:
In an application where external data memory is used and no
other outputs are active, power dissipation is calculated as
follows:
Assumptions:
External data memory is accessed every cycle with 50% of the
address pins switching.
External data memory writes occur every other cycle with
50% of the data pins switching.
Each address and data pin has a 10 pF total load at the pin.
The application operates at V
DD = 3.3 V and tCK = 50 ns.
Total Power Dissipation = PINT + (C × VDD
2
× f )
PINT = internal power dissipation from Power vs. Frequency
graph (Figure 18).
