This is the current drawn from VREGI, measured on 150 units with a while(1) loop executing, with all peripherals disabled, at 96MHz frequency, VREGI = 3.3V, 25°C.
Parameter | AVG | STDEV | AVG+3*STDEV | MAX | MIN |
Total Current (mA) | 3.284 | 0.054 | 3.444 | 3.390 | 3.140 |
Static Current (mA) | 0.664 | 0.027 | 0.828 | 0.732 | 0.604 |
On average, this would imply (3.284mA – 0.664mA)/96MHz or 27uA/MHz for active current.
The standard deviation is fairly tight and is expected for the active current which will be dominated by frequency in the standard equation for digital circuit power consumption: P = CV2f.
