PIN Description (continued)
PIN SYMBOL TYPE
DESCRIPTION
27 AUX
O
Auxiliary Output: This pin delivers analog test signals. The signal delivered on this
output may be selected by means of the TestAnaOutSel Register.
28 AVSS
PWR Analog Ground
29 RX
I
Receiver Input: Input pin for the labels response, which is the load modulated
13.56 MHz carrier frequenzy, that is coupled out from the antenna circuit.
30 VMID
Internal Reference Voltage: This pin delivers the internal reference voltage.
PWR
Note: It has to be supported by means of a 100 nF block capacitor.
31 RSTPD
Reset and Power Down: When HIGH, internal current sinks are switched off, the
I 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.
32 OSCOUT O Crystal Oscillator Output: Output of the inverting amplifier of the oscillator.
