VDD = 1.71 to 1.8 V(1)

1. 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.

2. To be USB compliant from the I/O voltage standpoint, the minimum VDD_USB is 3.0 V.

VDD = 2.4 to 3.6 V

Conversion time

up to
