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 V
DD
or V
SS
(no load).
• All peripherals are disabled except if it is explicitly mentioned.
• The Flash memory access time is adjusted both to f
HCLK
frequency and V
DD
range
(see Table 19: Limitations depending on the operating power supply range).
• When the regulator is ON, the voltage scaling and over-drive mode are adjusted to
f
HCLK
frequency as follows:
– Scale 3 for f
HCLK
≤ 144 MHz
– Scale 2 for 144 MHz < f
HCLK
≤ 168 MHz
– Scale 1 for 168 MHz < f
HCLK
≤ 216 MHz. The over-drive is only ON at 216 MHz.
• When the regulator is OFF, the V12 is provided externally as described in Table 18:
General operating conditions:
• The system clock is HCLK, f
PCLK1
= f
HCLK
/4, and f
PCLK2
= f
HCLK
/2.
• External clock frequency is 25 MHz and PLL is ON when f
HCLK
is higher than 25 MHz.
• The typical current consumption values are obtained for 1.7 V ≤
V
DD
≤ 3.6 V voltage
range and for T
A
= 25 °C unless otherwise specified.
• The maximum values are obtained for 1.7 V ≤
V
DD
≤ 3.6 V voltage range and a
maximum ambient temperature (T
A
) unless otherwise specified.
• For the voltage range 1.7 V ≤
V
DD
≤ 3.6 V, the maximum frequency is 180 MHz.
