Hi Nordic Team,
Does the reset of 54L15 need to be handled? Still pull up a 1k resistor. Also, do I need two wires for debugging?
The customer has another question. They want to use the nfc function. The usage scenario is that we are a portable tag with wireless charging function. The coil of the nfc and the wireless charging coil are on the same FFC and concentric, that is, in the same magnetic field.
If IC is entering deep sleep. When wireless charging comes in, will the ic mistake it for nfc and then start up? I asked the AI of your system. It seems that if it is awakened by nfc, it will reset, and there is also a protection device in nfc that will be disabled. In that case, would nfc be damaged in this scenario?
I want to reduce the impact of wireless charging on the nfc circuit. I want to connect two 50pf capacitors in series to the pins of the NFC. Is this feasible? A 50pf capacitor is placed between the ic and the resonant circuit.
