Supply current characteristics

The current consumption is measured as described in Figure 10: Current consumption

measurement scheme.

Maximum current consumption

The MCU is placed under the following conditions:

●

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

●

All peripherals are disabled except if it is explicitly mentioned

●

The Flash access time is adjusted to fHCLK frequency (0 wait state from 0 to 24 MHz, 1

wait state from 24 to 48 MHz and 2 wait states above)

The parameters given in Table 11 are derived from tests performed under ambient

temperature and VDD supply voltage conditions summarized in Table 7.
