On-chip peripheral current consumption
The current consumption of the on-chip peripherals is given in Table 28. The MCU is placed
under the following conditions:
•
At startup, all I/O pins are configured as analog pins by firmware.
•
All peripherals are disabled unless otherwise mentioned
•
The code is running from Flash memory and the Flash memory access time is equal to
5 wait states at 168 MHz.
•
The code is running from Flash memory and the Flash memory access time is equal to
4 wait states at 144 MHz, and the power scale mode is set to 2.
•
The ART accelerator is ON.
•
The given value is calculated by measuring the difference of current consumption
–
with all peripherals clocked off
–
with one peripheral clocked on (with only the clock applied)
•
When the peripherals are enabled: HCLK is the system clock, fPCLK1 = fHCLK/4, and
fPCLK2 = fHCLK/2.
•
The typical values are obtained for VDD = 3.3 V and TA= 25 °C, unless otherwise
specified.
