1. General description
NXP Semiconductors has developed MIFARE MF0ICU2 - MIFARE Ultralight C - to be
used with Proximity Coupling Devices (PCD) according to ISO/IEC 14443A (see Ref. 1
“ISO/IEC”). The communication layer (MIFARE RF Interface) complies to parts 2 and 3 of
the ISO/IEC 14443A standard. The MF0ICU2 is primarily designed for limited use
applications such as public transportation, event ticketing and NFC Forum Tag Type 2
applications.
1.1 Contactless energy and data transfer
In the MIFARE system, the MF0ICU2 is connected to a coil with a few turns. The
MF0ICU2 fits for the TFC.0 (Edmonson) and TFC.1 ticket formats as defined in EN 753-2.
TFC.1 ticket formats are supported by the MF0xxU20 chip featuring an on-chip resonance
capacitor of 16.9 pF.
The smaller TFC.0 tickets are supported by the MFxxU21 chip holding an on-chip
resonance capacitor of 50 pF.
When the ticket is positioned in the proximity of the coupling device (PCD) antenna, the
high speed RF communication interface allows the transmission of the data with a baud
rate of 106 kbit/s.
1.2 Anticollision
An intelligent anticollision function according to ISO/IEC 14443 allows to operate more
than one card in the field simultaneously. The anticollision algorithm selects each card
individually and ensures that the execution of a transaction with a selected card is
performed correctly without data corruption resulting from other cards in the field.
