Do all NuMicro® Cortex-M0 Series provide the USB functions?

[Henry]

No, the USB function is only included in some NuMicro® Series chips, such as the NUC120 series, Nano120 series, M452 series and so on.
Also, the NuMicro® family includes many kinds of series that can be used for different applications, such as USB applications, motor control, power management, etc.
Please refer to Online Products Selection for choosing what series is suitable for USB applications.
