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 VDD or VSS (no load)

● All peripherals are disabled except if it is explicitly mentioned

● The Flash access time is adjusted to fHCLK frequency (0 wait state from 0 to 24 MHz, 1

wait state from 24 to 36 MHz)

● Prefetch is on (reminder: this bit must be set before clock setting and bus prescaling)

● When the peripherals are enabled fPCLK1 = fHCLK/4, fPCLK2 = fHCLK/2, fADCCLK =

fPCLK2/4

The parameters given in Table 16 are derived from tests performed under the ambient

temperature and VDD supply voltage conditions summarized in Table 8.

1. Typical values are measures at TA = 25 °C, VDD = 3.3 V.

2. Add an additional power consumption of 0.8 mA per ADC for the analog part. In applications, this

consumption occurs only while the ADC is on (ADON bit is set in the ADC_CR2 register).

3. External clock is 8 MHz and PLL is on when fHCLK > 8 MHz.
