The AT88SC3216CRF contains 32 Kbits of user memory and 2 Kbits of configuration memory. The 2 Kbits of configuration
memory contain eight sets of read/write passwords, four crypto key sets, security access registers for each user zone, and
password/key registers for each zone.
The CryptoRF command set is optimized for a multicard RF communications environment. A programmable AFI register
allows this IC to be used in numerous applications in the same geographic area with seamless discrimination of cards
assigned to a particular application during the anticollision process.

3. Communications
All personalization and communication with this device is performed through the RF interface.
The IC includes an integrated tuning capacitor, enabling it to operate with only the addition of a
single external coil antenna.
The RF communications interface is fully compliant with the electrical signaling and RF power
specifications in ISO/IEC 14443-2:2001 for Type B only. Anticollision operation and frame for-
matting are compliant with ISO/IEC 14443-3:2001 for Type B only.
ISO/IEC 14443 nomenclature is used in this specification where applicable. The following abbre-
viations are utilized throughout this document. Additional terms are defined in the section in
which they are used.
• PCD – Proximity Coupling Device: the reader/writer and antenna
• PICC – Proximity Integrated Circuit Card: the tag/card containing the IC and antenna
