14. Application information
The slow input rise and fall times cause additional power dissipation, which can be
calculated using the following formula:
Padd =f
i×(tr×∆ICC(AV) +t
f×∆ICC(AV))×VCC where:
Padd = additional power dissipation (µW);
fi= input frequency (MHz);
tr= input rise time (ns); 10 % to 90 %;
tf= input fall time (ns); 90 % to 10 %;
∆ICC(AV) = average additional supply current (µA).
Average additional ICC differs with positive or negative input transitions, as shown in
Figure 11.
For XC7SET14 used in relaxation oscillator circuit, see Figure 12.
Note to the application information:
