HF interface for 13.56 MHz transponders
•
Prox interface for 125 kHz transponders (SE32x0APx only)
6.1
HF Interface (13.56 MHz)
The HF interface is optimized for operation with 50Ω tuned antennas.

The impedance of 50Ω allows for integrated antennas, as well as remote antennas
The impedance of 50Ω allows for integrated antennas, as well as remote antennas
connected through a coax cable. Use a coaxial connection whenever operating the module in
Normal Power Mode, if possible.
