DESCRIPTION

Address Line 1: Bit 1 of register address

Address Line 2: Bit 2 of register address

SCK

Serial Clock: Clock for the SPI interface

DVDD

PIWR Digital Power Supply

AVDD

PWR

Analog Power Supply

AUX

Auxiliary Output: This pin delivers analog test signals. The signal delivered on this

output may be selected by means of the TestAnaOutSel Register.

AVSS

PWR

Analog Ground

Receiver Input: Input pin for the cards response, which is the load modulated 13.56

MHz energy carrier, that is coupled out from the antenna circuit.

VMID

PWR

Internal Reference Voltage: This pin delivers the internal reference voltage.

Note: It has to be supported by means of a 100 nF block capacitor.

RSTPD

Reset and Power Down: When HIGH, internal current sinks 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.

OSCOUT

Crystal Oscillator Output: Output of the inverting amplifier of the oscillator.
