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, f
PCLK1
= f
HCLK
/4, and
f
PCLK2
= f
HCLK
/2.
The typical values are obtained for V
DD
= 3.3 V and T
A
= 25 °C, unless otherwise
specified.
