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.
