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 both to fHCLK frequency and VDD range

(see Table 18: Limitations depending on the operating power supply range).

•

When the regulator is ON, the voltage scaling and over-drive mode are adjusted to

fHCLK frequency as follows:

–

Scale 3 for fHCLK ≤ 144 MHz

–

Scale 2 for 144 MHz < fHCLK ≤ 168 MHz

–

Scale 1 for 168 MHz < fHCLK ≤ 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 17:

General operating conditions:

•

The system clock is HCLK, fPCLK1 = fHCLK/4, and fPCLK2 = fHCLK/2.

•

External clock frequency is 25 MHz and PLL is ON when fHCLK is higher than 25 MHz.

•

The typical current consumption values are obtained for 1.7 V

≤ VDD ≤ 3.6 V voltage

range and for TA= 25 °C unless otherwise specified.

•

The maximum values are obtained for 1.7 V

≤ VDD ≤ 3.6 V voltage range and a

maximum ambient temperature (TA) unless otherwise specified.

•

For the voltage range 1.7 V

≤ VDD ≤ 3.6 V, the maximum frequency is 180 MHz.
