4. PN5180 hardware design
The PN5180 is optimized to support the NFC, ISO and EMVCo with a minimum of
additional components. The PN5180 simply requires the antenna matching circuitry,
some block capacitors and the crystal.
However, the calculation and tuning of the matching components need to be done
carefully to provide the full performance as well as to meet CE and FCC regulations.
The Fig 18 and Fig 19 show a typical analog circuitry using the PN5180.
