HI everybody

about Vpp , pn page 22 of datasheet I can see --"During normal operation, no voltage should be applied to VPP. "

so should I leave the pin unconnected in std usage ? or should I have a pull up or down ?

could you kindly elaborate a little ?

thank you

Hi Carlo,
It standard use case VPP pin should be left as NOT CONNECTED (NC) .

Please see the EVM schematic. Customer can add 0.1uF capacitor on VPP pin in the case of High Secure devices.

Thanks and Regards,
