The parameters given in
Table 11 are derived from tests performed under ambient
temperature and VDD supply voltage conditions summarized in Table 8. 5.3.5
Supply current characteristics
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 36 MHz)
●
Prefetch in on (reminder: this bit must be set before clock setting and bus prescaling)
●
When the peripherals are enabled fPCLK1 = fHCLK/2, fPCLK2 = fHCLK
The parameters given in
Table 12 are derived from tests performed under ambient
temperature and VDD supply voltage conditions summarized in Table 8. Table 11.
