Calculating Power Dissipation
Quiescent Supply Current
Quiescent supply current (IDD) calculation depends on multiple factors, including operating voltages
(VCC, VCCI, and VJTAG), operating temperature, system clock frequency, and power modes usage.
Microsemi recommends using the PowerCalculator and SmartPower software estimation tools to
evaluate the projected static and active power based on the user design, power mode usage, operating
voltage, and temperature.
