Short Product Information
Analog Contactless Interface:
The Analog Contactless Interface comprises the voltage rectifier, voltage regulator and system
clock to supply the IC with appropriate power. Additionally the data stream is modulated and
demodulated.
Operational mode
The access to the memory depends on the actual mode of the my-d
accessed according to plain or secure mode after the VICC is selected.
Authentication Unit (optional use)
The Authentication Unit generates random numbers, calculates and verifies the message
authentication codes (MAC).
Memory Unit
The Memory Unit consists of 1280 bytes organised in 128 pages each of 8 user and 2
administration bytes.
