Can it work as USB device on 1.8V (VDD), with separate regulator for 3.3V on VDD_USB?
How pulling of D+ over 1.5k to 3.3V is done (internaly maybe)?
If there is other performance limitation regarding working on low voltage (1.8V)?
If USB internal clock generator (crystalless) can be used as USB device 32 MHz CPU/buss precise clock source?
