Electrical characteristics
10.3.2
Supply current characteristics
The current consumption is measured as described in Figure 9 on page 51.
Total current consumption in run mode
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 (clock stopped by Peripheral Clock Gating registers) except
if explicitly mentioned.
● When the MCU is clocked at 24 MHz, TA ≤105 °C and the WAITSTATE option bit is set.
Subject to general operating conditions for VDD and TA.
