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.
