8.3.5 EPC-UID/UID-OTP functionality
The physical parameters are described in Table 11.
Data coding and framing according to EPC global 13.56 MHz ISM (industrial, scientific
and medical) Band Class 1 Radio Frequency Identification Tag Interface Specification
(Candidate Recommendation, Version 1.0.0).
8.3.6 ISO/IEC 18000-3 mode 3/ EPC Class-1 HF functionality
The ISO/IEC 18000-3 mode 3/ EPC Class-1 HF is not described in this document. For a
detailed explanation of the protocol, refer to the ISO/IEC 18000-3 mode 3/ EPC Class-1
HF standard.
8.3.7 ISO/IEC 18092 mode
The CLRC663 supports Passive Initiator Communication mode at the transfer speeds
106 kbit/s, 212 kbit/s and 424 kbit/s as defined in the ISO/IEC 18092 standard.
Passive communication mode means that the target answers to an initiator command
in a load modulation scheme. The initiator is active in terms of generating the RF field.
Initiator: generates RF field at 13.56 MHz and starts the ISO/IEC 18092
communication.
Target: responds to initiator command either in a load modulation scheme in Passive
communication mode or using a self generated and self modulated RF field for Active
Communication mode.
