On-chip peripheral current consumption
The MCU is placed under the following conditions:
• At startup, all I/O pins are in analog input configuration.
• All peripherals are disabled unless otherwise mentioned.
• The ART accelerator is ON.
• Voltage Scale 2 mode selected, internal digital voltage V12 = 1.26 V.
• HCLK is the system clock at 100 MHz. f
PCLK1
= f
HCLK
/2, and f
PCLK2
= f
HCLK
.
The given value is calculated by measuring the difference of current consumption
– with all peripherals clocked off
– with only one peripheral clocked on
• Ambient operating temperature is 25 °C and V
DD
=3.3 V.
