5.3.7 Supply current characteristics
The current consumption is a function of several parameters and factors such as operating
voltage, ambient temperature, I/O pin loading, device software configuration, operating
frequencies, I/O pin switching rate, program location in memory and executed binary code.
The current consumption is measured as described in Figure 12.
Typical and maximum current consumption
The device is put 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 with the minimum wait-states number,
depending on the f
HCLK
frequency. Refer to the table ‘Number of wait states according
to Flash clock (HCLK3) frequency’ in the reference manual (RM0461).

for the Flash memory and shared peripherals.
Parameters given in the tables below (Table 35 to Table 47) are derived from tests
performed under ambient temperature and supply voltage conditions summarized in
Table 25: General operating conditions.
