Electrical characteristics

Typical and maximum current consumption

The MCU is put under the following conditions:

•

All I/O pins are in analog input mode

•

All peripherals are disabled, except when otherwise mentioned

•

The flash memory and SRAM access time is adjusted with the minimum wait states

number, depending upon the fHCLK frequency (refer to tables in the reference manual).

•

When the peripherals are enabled fPCLKx = fHCLK1

•

The voltage scaling is adjusted to fHCLK frequency as follows:

–

Voltage range 1 for 16 MHz < fHCLK1 ≤ 100 MHz and 12 MHz < fHCLK5 ≤ 32 MHz

–

Voltage range 2 for fHCLK1 ≤ 16 MHz and fHCLK5 ≤ 12 MHz

The parameters given in Table 44 and Table 45 are evaluated by characterization under

ambient temperature and supply voltage conditions summarized in Table 30.
