Typical and maximum current consumption

The MCU is placed under the following conditions:

•

All I/O pins are in analog input mode

•

All peripherals are disabled except when explicitly mentioned

•

The Flash memory access time is adjusted to the fHCLK frequency:

–

0 wait state and Prefetch OFF from 0 to 24 MHz

–

1 wait state and Prefetch ON above 24 MHz

•

When the peripherals are enabled fPCLK = fHCLK

The parameters given in Table 24 to Table 26 are derived from tests performed under

ambient temperature and supply voltage conditions summarized in Table 20: General

operating conditions.
