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 V
DD
or V
SS
(no load).
All peripherals are disabled except if it is explicitly mentioned.
The
Flash
access time is adjusted to f
HCLK
frequency (0 wait state from 0 to 24 MHz, 1
wait state from 24 to 48 MHZ and 2 wait states above).
