6.3.6 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 18: Current consumption
measurement scheme.
All the run-mode current consumption measurements given in this section are performed
with a reduced code that gives a consumption equivalent to CoreMark code.
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 f
HCLK
frequency and VDD ranges
(refer to Table 15: Features depending on the operating power supply range).
• The voltage scaling is adjusted to f
HCLK
frequency as follows:
– Scale 3 for f
HCLK
≤ 64 MHz
– Scale 2 for 64 MHz < f
HCLK
≤ 84 MHz
– Scale 1 for 84 MHz < f
HCLK
≤ 100 MHz
• The system clock is HCLK, f
PCLK1
= f
HCLK
/2, and f
PCLK2
= f
HCLK
.
• External clock is 4 MHz and PLL is ON except if it is explicitly mentioned.
• The maximum values are obtained for V
DD
= 3.6 V and a maximum ambient
temperature (T
A
), and the typical values for T
A
= 25 °C and V
DD
= 3.3 V unless
otherwise specified.

1. The product behavior is guaranteed by design down to the minimum V
POR/PDR
value.
2. Guaranteed by design.
3. The reset timing is measured from the power-on (POR reset or wakeup from V
BAT
) to the instant when first
instruction is fetched by the user application code.
