Supply current of resonator

oscillator(2)(3)

Data based on characterization results done with the external components specified in Section 20.5.1:

Crystal and ceramic resonator oscillators, not tested in production.

As the oscillator is based on a current source, the consumption does not depend on the voltage.

IDD(TIM) 16-bit timer supply current

(1)

Data based on a differential IDD measurement between reset configuration (timer counter running at

fCPU/4) and timer counter stopped (only TIMD bit set). Data valid for one timer.

VDD = 5.0V

µA

IDD(TIM8) 8-bit timer supply current

(1)

IDD(ART) ART PWM supply current

(2)

Data based on a differential IDD measurement between reset configuration (timer stopped) and timer

counter enabled (only TCE bit set).

IDD(SPI) SPI supply current

(3)

Data based on a differential IDD measurement between reset configuration (SPI disabled) and a permanent

SPI master communication at maximum speed (data sent equal to 55h).This measurement includes the

pad toggling consumption.

400

IDD(SCI) SCI supply current

(4)

Data based on a differential IDD measurement between SCI low power state (SCID = 1) and a permanent

SCI data transmit sequence. Data valid for one SCI.

IDD(ADC) ADC supply current when converting

(5)

Data based on a differential IDD measurement between reset configuration and continuous A/D

conversions.

IDD(CAN) CAN supply current

(6)

Data based on a differential IDD measurement between reset configuration (CAN disabled) and a

permanent CAN data transmit sequence with RX and TX connected together. This measurement include

the pad toggling consumption.
