Electrical characteristics

Typical 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).

●

Ambient temperature and VDD supply voltage conditions summarized in Table 7.

Table 13.

Typical current consumption in Run and Sleep modes(1)

TBD stands for to be determined.
