Supply current characteristics
The current consumption is measured as described in Figure 6 and Figure 7.
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.
Table 9.
Total Current consumption
Notes:
1.
Typical data are based on TA=25°C, VDD=5V
2.
Data based on characterization results, tested in production at VDD max. and TA = 25°C.
3.
I/O in static configuration (not toggling). RUN mode is almost independent of temperature. On the
contrary RUN mode current is highly dependent on the application. The IDDRUN value can be
significantly reduced by the application in the following ways: switch-off unused peripherals (default),
reduce peripheral frequency through internal prescaler, fetch the most frequently-used functions from RAM
and use low power mode when possible.
