Supply current characteristics

The current consumption is a function of several parameters and factors such as the
operating voltage, 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
measurement
All Run-mode current consumption measurements given in this section are performed with a
reduced code that gives a consumption equivalent to the Dhrystone 2.1 code, unless
otherwise specified. The current consumption values are derived from tests performed
under ambient temperature T
Table 12: General operating
The MCU is placed under the following conditions:
•
All I/O pins are configured in analog input mode
•
All peripherals are disabled except when explicitly mentioned.
•
The Flash memory access time, 64-bit access and prefetch is adjusted depending on
f
HCLK
•
When the peripherals are enabled f
•
When PLL is ON, the PLL inputs are equal to HSI = 16 MHz (if internal clock is used) or
HSE = 16 MHz (if HSE bypass mode is used).
•
The HSE user clock applied to OSCI_IN input follows the characteristic specified in
Table 25: High-speed external user clock

•
For typical current consumption V
