Electrical characteristics
PWM current consumption overview
The figures that follow provide an outline view of PWM current consumption results.The
consumptions are evaluated considering the maximum current at T
A
= 25 °C with different
SMED operating frequencies. The charts summarize the measurements carried out from

1.
SMED frequency:
-
96 MHz and 6 MHz frequencies require the PLL enabled.
-
Current table shows only a subset value of possible SMED frequencies.
2.
PWM frequency:
-
PWM toggle frequency is considered fixed to 500 kHz, close to the maximum applicative value.
3.
ADC frequency:
-
6 MHz frequency requires the PLL enabled.
-
Current table shows only a subset value of possible ADC frequencies.
4.
Number of active PWMs.
5.
PWM pins are loaded with a CL (load capacitance) of 50 pF.
6.
If enabled all DACs and comparator units are active.
7.
ADC configured in circular mode.
8.
Temperature operating: TA= 25 °C.
9.
Data based on characterization results not tested in production.
