Notes: 1. The external loads on PIOs are not taken into account in the calculation.
2. Supply Monitor current consumption is not included.
3. When considering wake-up time, the time required to start the PLL is not taken into account. Once started, the device works with the 4/8/12 MHz fast RC
3. When considering wake-up time, the time required to start the PLL is not taken into account. Once started, the device works with the 4/8/12 MHz fast RC
oscillator. The user has to add the PLL start-up time if it is needed in the system. The wake-up time is defined as the time taken for wake up until the first
instruction is fetched.
4. Total consumption 1 µA typ to 1.8V on VDDIO at 25°C.
5. 20.4 µA on VDDCORE, 32.2 µA for total current consumption.
6. Depends on MCK frequency.
7. Depends on MCK frequency. In this mode, the core is supplied but some peripherals can be clocked.
