Description
Digital Ground
Load Modulation output provides digital signal for FeliCa and MIFARE®
card operating mode
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: Input pin for the reception signal, which is the load
modulated 13.56 MHz energy carrier from the antenna circuit.
Analog Ground
Auxiliary Output: This pin delivers analog and digital test signals.
Auxiliary Output: This pin delivers analog and digital test signals.
Crystal Oscillator Input: input to the inverting amplifier of the oscillator. This
pin is also the input for an externally generated clock (fosc = 27.12 MHz).
Crystal Oscillator output: Output of the inverting amplifier of the oscillator.
Interface mode lines: selects the used host interface. In test mode I0 is
used as test signals.
Interface mode lines: selects the used host interface. In test mode I0 is
used as test signals.
Test enable pin: When set to 1 enable the test mode. When set to 0 reset
the TCB and disable the access to the test mode.
Crystal Oscillator output: Output of the inverting amplifier of the oscillator
for the USB clock.
Crystal Oscillator Input: input to the inverting amplifier of the oscillator for
the USB clock generation. This pin is also the input for an externally
generated clock (f
