The AT88RF04C contains 4 Kbits of user memory and 2 Kbits of configuration memory. The 2 Kbits of configuration memory
contain four 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 multi-card 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.

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 formatting 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 abbreviations 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
• RFU – Reserved for Future Use: any feature, memory location, or bit that is held as reserved for future use
• $ xx – Hexadecimal Number: denotes a hex number “xx” (Most Significant Bit on left)
