NOTES: 1. G�aranteed by desi�n� not tested in prod�ction.

2. To be compliant with the USB 2.0 full-speed electrical specification, the USBDP pin should be pulled

up with a 1.5kΩ external resistor to a 3.0 to 3.6V voltage supply.

3. The USB f�nctionality is ens�red down to �.7V b�t not the f�ll USB electrical characteristics which will

experience de�radation in the �.7 to �.0V VDD volta�e ran�e.

4. RL is the load connected to the USB driver USBDP.
