Near Field Communication (NFC) controller
12.3 Current consumption characteristics
[1] Typical value using a complementary driver configuration and an antenna matched to 40  between TX1
and TX2 at 13.56 MHz.
[2] IPV
DD
depends on the overall load at the pins. The maximum is given assuming 4mA output current for the
I/O or output pads.
[3] ISV
DD
depends on the overall load on SV
DD
pad.
[4] During operation with recommended antenna tuning circuitry the overall current is below 100 mA.
[5] ISPD and IHPD are the total currents across all supplies with the PN532xA3HN/C104 and
PN532xA3HN/C105.
[6] The antenna should be tuned not to exceed this current limit (the detuning effect when coupling with
another device must be taken into account)
[7] These values are valid when applied the Soft-Power-Down sequence described in Section 8.5.4 on
page 92, and with TESTEN pin connected to DVSS.
