Electrical characteristics

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.
•
I/O compensation cell enabled.
•
The ART accelerator is ON.
•
Scale 1 mode selected, internal digital voltage V12 = 1.32 V.
•
HCLK is the system clock. fPCLK1 = fHCLK/4, and fPCLK2 = fHCLK/2.
The given value is calculated by measuring the difference of current consumption
–
with all peripherals clocked off
–
with only one peripheral clocked on
–fHCLK = 180 MHz (Scale1 + over-drive ON), fHCLK = 144 MHz (Scale 2),
fHCLK = 120 MHz (Scale 3)"
•
Ambient operating temperature is 25 °C and VDD=3.3 V.
