Introduction
The CryptoRF family consists of devices in the AT88SCxxxxCRF and AT88RFxxC catalog number series. The first
generation devices are assigned catalog numbers in the AT88SCxxxxCRF series. The second generation devices are
assigned catalog numbers in the AT88RFxxC series. Several security options have been added to the second
generation devices to enhance system security.
1.1.
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 for Type B only. Anticollision operation and frame formatting are compliant with ISO/IEC 14443-3 for Type B
only.
1.2.
Scope
This
CryptoRF Specification
document includes all specifications for the Normal, Authentication, and Encryption modes
of CryptoRF operation.
1.3.
Conventions
ISO/IEC 14443 nomenclature is used in this specification where applicable. The following abbreviations are utilized
throughout this document. Additional terms are defined in Appendix A.
Proximity Coupling Device – is the reader/writer and antenna.
Proximity Integrated Circuit Card – is the tag/card containing the IC and antenna.
Reserved for Future Use – is any feature, memory location, or bit that is held as reserved for future use by
the ISO standards committee or by Atmel.
•
$xx:
Hexadecimal Number – denotes a hex number “xx” (Most Significant Bit on left).
•
xxxxb:
Binary Number – denotes a binary number “xxxx” (Most Significant Bit on left).
•
88SC:
CryptoRF devices in the AT88SCxxxxCRF catalog number series.
•
88RF:
CryptoRF devices in the AT88RFxxC catalog number series.
This document contains the specifications for AT88SCxxxxCRF and AT88RFxxC CryptoRF devices. Any specification
that applies only to first generation AT88SCxxxxCRF devices references: "88SC" devices, "88SC" PICCs, or contain
"[88SC]" in the section title. Any specification that applies only to second generation AT88RFxxC devices references:
"88RF" devices, "88RF" PICCs, or contain "[88RF]" in the section title. Specifications that apply to all devices are
referred to as CryptoRF specifications.
Each command / response exchange between the PCD and PICC is formatted as shown in Figure 2. The bytes are
shown in the order in which they are transmitted, with PCD transmissions in the left column, and PICC transmissions in
