Electrical characteristics
Typical and maximum 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 memory access time is adjusted to both fHCLK frequency and VDD ranges
(refer to Table 15: Features depending on the operating power supply range).
• The voltage scaling is adjusted to fHCLK frequency as follows:
– Scale 3 for fHCLK ≤ 60 MHz
– Scale 2 for 60 MHz < fHCLK ≤ 84 MHz
• The system clock is HCLK, fPCLK1 = fHCLK/2, and fPCLK2 = fHCLK.
• External clock is 4 MHz and PLL is on when fHCLK is higher than 25 MHz.
• The maximum values are obtained for VDD = 3.6 V and a maximum ambient
temperature (TA), and the typical values for TA= 25 °C and VDD = 3.3 V unless
otherwise specified.

1. Guaranteed by characterization, unless otherwise specified.
2. When analog peripheral blocks such as ADC, HSE, LSE, HSI, or LSI are ON, an additional power consumption has to be
considered.
3. When the ADC is ON (ADON bit set in the ADC_CR2 register), add an additional power consumption of 1.6 mA for the
analog part.
4. Guaranteed by test in production.
