Using different antenna matching circuits (by varying the supply voltage on the antenna
driver supply pin TVDD), it is possible to find the trade-off between maximum effective
operating distance and power consumption. Different antenna matching circuits are
described in the Application note “MIFARE Design of MFRC500 Matching Circuit and
Antennas”.
The output source conductance of pins TX1 and TX2 can be adjusted between 1 Ω and
100 Ω using the CwConductance register GsCfgCW[5:0] bits.
The output source conductance of pins TX1 and TX2 during the modulation phase can be
adjusted between 1 Ω and 100 Ω using the ModConductance register GsCfgMod[5:0] bits.
The values are relative to the reference resistance (R
production test and stored in the MFRC500 EEPROM. It can be read from the product
information field (see
