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 VDD = 5.0 V and tCK = 30 ns.
Total Power Dissipation = PINT + (C
× VDD2 × f)
PINT = internal power dissipation from Power vs. Frequency
graph (Figure 23).
(C
× VDD2 × f) is calculated for each output:
