16 / 124 page  Functional overview STM32L062x8 16/124 DS10183 Rev 11 Table 2. Functionalities depending on the operating power supply range Operating power supply range(1) 1. GPIO speed depends on VDD voltage range. Refer to Table 53: I/O AC characteristics for more information about I/O speed. Functionalities depending on the operating power supply range DAC and ADC operation Dynamic voltage scaling range USB VDD = 1.65 to 1.71 V ADC only, conversion time up to 570 ksps Range 2 or range 3 Not functional VDD = 1.71 to 1.8 V(2) 2. CPU frequency changes from initial to final must respect "fcpu initial <4*fcpu final". It must also respect 5 μs delay between two changes. For example to switch from 4.2 MHz to 32 MHz, you can switch from 4.2 MHz to 16 MHz, wait 5 μs, then switch from 16 MHz to 32 MHz. ADC only, conversion time up to 1.14 Msps Range 1, range 2 or range 3 Functional VDD = 1.8 to 2.0 V(2) Conversion time up to 1.14 Msps Range1, range 2 or range 3 Functional VDD = 2.0 to 2.4 V Conversion time up to 1.14 Msps Range 1, range 2 or range 3 Functional VDD = 2.4 to 3.6 V Conversion time up to 1.14 Msps Range 1, range 2 or range 3 Functional Table 3. CPU frequency range depending on dynamic voltage scaling CPU frequency range Dynamic voltage scaling range 16 MHz to 32 MHz (1ws) 32 kHz to 16 MHz (0ws) Range 1 8 MHz to 16 MHz (1ws) 32 kHz to 8 MHz (0ws) Range 2 32 kHz to 4.2 MHz (0ws) Range 3 Table 4.
