8 Communication
8.1.1 RFID analog front-end
The MLX90129 RFID interface complies with the ISO15693 requirements. It is accessed by the RFID base-
station (reader) in modulating the 13.56 MHz carrier frequency. The data are recovered from the signal
amplitude modulation (ASK, Amplitude Shift Keying 10% or 100%). The Data transfer rate is 26 kBit/s using
the 1/4 pulse-coding mode.
The outgoing data are generated by an antenna load variation, using the Manchester coding, and using one
or two sub-carrier frequencies at 423 kHz and 484 kHz. The data transfer rate is 26 k-Bit/s. From the
incoming field, the RFID interface recovers the clock and makes its own power supply. The rectified voltage
may also be used to supply the whole device in battery-less applications.
8.1.2 ISO-15693 Features and Command set
For complete information about the communication protocol, please refer to the standard document:
ISO/IEC FCD 15693-2 and ISO/IEC FCD 15693-3: Identification cards- contactless integrated circuit(s)
cards - Vicinity cards - It is available on the website:
Some of the features of the protocol are not supported. Furthermore, some “custom” commands have been
defined (see Command set). The MLX90129 is provided with a Unique IDentifier compliant with the ISO
standard.
