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 14. Current consumption measurement scheme.

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 fHCLK frequency (refer to the table “Number of

wait states according to CPU clock (HCLK) frequency” available in the RM0503 reference manual).

•

When the peripherals are enabled fPCLK = fHCLK

The parameters given in Table 26 to Table 43 are derived from tests performed under ambient temperature and supply voltage conditions summarized in

Section 6.3.1: General operating conditions.
