2. Introduction
The CryptoRF family consists of devices in the AT88SCxxCRF and AT88RFxxC catalog number series. The first
generation devices are assigned catalog numbers in the AT88SCxxCRF 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.
2.1 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.
2.2 Scope
This CryptoRF Specification document includes all specifications for the Normal, Authentication, and Encryption modes
of CryptoRF operation.
2.3 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 “Terms and Abbreviations” on page 70.

This document contains the specifications for AT88SCxxCRF and AT88RFxxC CryptoRF devices. Any specification that
applies only to the first generation AT88SCxxCRF devices references: 88SC devices, 88SC PICCs, or contain [88SC] in
the section title. Any specification that applies only to the 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 2-1. The bytes are
shown in the order in which they are transmitted, with PCD transmissions in the left column, and PICC transmissions in
the right column.
