Unit

IDD(TIM)

TIM Timer supply current (1)

Data based on a differential IDD measurement between reset configuration and timer counter running at 32

MHz. No IC/OC programmed (no I/O pads toggling)

0.7

IDD(PWM)

PWM Timer supply current(2)

Data based on a differential IDD measurement between reset configuration and PWM running at 32 MHz.

This measurement does not include PWM pads toggling consumption.

IDD(SSP)

SSP supply current (3)

Data based on a differential IDD measurement between reset configuration and permanent SPI master

communication at maximum speed 16 MHz. The data sent is 55h. This measurement does not include the

pad toggling consumption.

1.3

IDD(UART)

UART supply current (4)

Data based on a differential IDD measurement between reset configuration and a permanent UART data

transmit sequence at 1Mbauds. This measurement does not include the pad toggling consumption.

1.6

IDD(I2C)

I2C supply current (5)

Data based on a differential IDD measurement between reset configuration (I2C disabled) and a permanent

I2C master communication at 100kHz (data sent equal to 55h). This measurement includes the pad

toggling consumption but not the external 10kOhm external pull-up on clock and data lines.

0.3

IDD(ADC)

ADC supply current when converting (6)

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

conversions at 8 MHz in scan mode on 16 inputs configured as AIN.

1.2

IDD(USB)

USB supply current (7)

Note: VDD_IO must be 3.3 V ±10%

Data based on a differential IDD measurement between reset configuration and a running generic HID

application.

0.90

IDD(CAN)

CAN supply current (8)

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

permanent CAN data transmit sequence in loopback mode at 1MHz. This measurement does not include

the pad toggling consumption.
