Supply current characteristics

The current consumption is measured as described in Figure 9 on page 32 and Figure 10

on page 32.

Total current consumption

The MCU is placed under the following conditions:

●

All I/O pins in input mode with a static value at V33 or VSS (no load)

●

All peripherals are disabled except if explicitly mentioned.

●

Embedded Regulators are used to provide 1.8V (except if explicitly

mentioned)

Subject to general operating conditions for V33, and TA.

Notes:

Typical data are based on TA=25°C, V33=3.3V.

Data based on characterization results, tested in production at V33, fMCLK max. and TA max.

Based on device characterisation, device power consumption in STOP mode at TA 25°C is predicted to be

30µA or less in 99.730020% of parts.

The conditions for these consumption measurements are described in application note AN2100.
