Description
Address Line
Pad power supply
Digital Power Supply
Digital Ground
Pad power supply ground
Not Reset and Power Down: When LOW, internal current sinks are switched off, the
oscillator is inhibited, and the input pads are disconnected from the outside world. With
a positive edge on this pin the internal reset phase starts.
Communication Interface Input: accepts a digital, serial data stream
Communication Interface Output: delivers a serial data stream
S
Transmitter Ground: supplies the output stage of TX1 and TX2
Transmitter 1: delivers the modulated 13.56 MHz energy carrier
Transmitter Power Supply: supplies the output stage of TX1 and TX2
Transmitter 2: delivers the modulated 13.56 MHz energy carrier
Transmitter Ground: supplies the output stage of TX1 and TX2
Analog Power Supply
Internal Reference Voltage: This pin delivers the internal reference voltage.
Receiver Input
Analog Ground
Auxiliary Outputs: These pins are used for testing.
Crystal Oscillator Input: input to the inverting amplifier of the oscillator. This pin is
also the input for an externally generated clock (f
Crystal Oscillator Output: Output of the inverting amplifier of the oscillator.
Interrupt Request: output to signal an interrupt event
Not Write: strobe to write data (applied on D0 to D7) into the PN512 register
Not Read: strobe to read data from the PN512 register (applied on D0 to D7)
Address Latch Enable: signal to latch AD0 to AD5 into the internal address latch
when HIGH.
Not Chip Select: selects and activates the host controller interface of the PN512
8-bit Bi-directional Data Bus.
Remark: For serial interfaces this pins can be used for test signals or I/Os.
Remark: If the host controller selects I
can be used to define the I
