6.3.6 Supply current characteristics
The current consumption is a function of several parameters and factors such as the
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 10: Current consumption
measurement scheme.
All the run-mode current consumption measurements given in this section are performed
with a CoreMark code.
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 with the minimum wait states number,
depending on the f
ACLK
frequency (refer to the table “Number of wait states according to
CPU clock (f
rcc_c_ck
) frequency and V
CORE
range” available in the reference manual).
• When the peripherals are enabled, the AHB clock frequency is the CPU frequency
divided by 2 and the APB clock frequency is AHB clock frequency divided by 2.
The parameters given in Table 28 to Table 36 are derived from tests performed under
ambient temperature and supply voltage conditions summarized in Table 22: General
operating conditions.
