Description
General purpose IO signal.Can be configured to act either as TX line of the
second serial interface or general purpose IO.
In test mode this signal is used as input and output test signal.
General purpose IO signal. Can be used to generate an HZ state on the
output of the selected interface for the Host communication and to enter
PN532 into powerdown mode without reseting the internal state of PN532.
In test mode this signal is used as input and output test signal.
General purpose IO signal. Can also be used as an interrupt source
In test mode this signal is used as input and output test signal.
General purpose IO signal or clk signal for the SAM
Contactless communication interface output: delivers a serial data stream
according to NFCIP-1 and output signal for the SAM.
In test mode this signal is used as test signal output.
Contactless communication interface input: accepts a digital, serial data
stream according to NFCIP-1 and input signal from the SAM.
In test mode this signal is used as test signal input.
Output power for SAM power supply. Switched on by Firmware with an
overload detection. Used as a reference voltage for SAM communication.
Reset and Power Down: When Low, internal current sources are switched off,
the oscillator is inhibited, and the input pads are disconnected from the
outside world.
With a negative edge on this pin the internal reset phase starts.
Internal Digital Power Supply
Main external power supply.
