Supply current characteristics

Total current consumption

The MCU is placed under the following conditions:

●

All I/O pins in input mode with a static value at VDD or VSS (no load)

●

All peripherals are disabled except if explicitly mentioned.

Subject to general operating conditions for VDD and TA.

Typical current consumption measured with code executed from Flash.

Table 18.

Total current consumption in Run mode (1)

Based on characterization results, unless otherwise specified.

Symbol

Parameter

Conditions(2)

All peripherals off, VDD from 1.65 V to 3.6 V, HSI internal RC osc. , fCPU=fMASTER

Typ

Max(3)

Maximum values are given for TA = −40 to 125 °C.

mode(4) (5)

CPU executing typical data processing.

An approximate value of IDD(Run) can be given by the following formula:

IDD(Run) = fMASTER x 150 µA/MHz +215 µA.
