I want to design an electronic device with the LPC54S018JxM microcontroller and the PN5180 module.
The power source of the system will be a 3.6V battery and / or the energy of an NFC field provided by the PN5180 module.
In document 436534 describing the PN5180 module, the electrical characteristics of the VDHF pin are not well documented and there is no explanation of how the microcontroller can be powered from this pin (possibly dual: battery / NFC power).
Is there more detailed documentation on this issue?
Is there an application schematics to help me?
