MHz RFID Sensor TAG Transponder IC
The MLX90129 combines a precise acquisition chain for external resistive sensors,
with a wide range of interface possibilities. It can be accessed and controlled
through its ISO15693 RFID front-end or via its SPI port. Without any other component
than a 13.56MHz tuned antenna, it becomes a RFID thermometer. For measuring other
physical quantities, one or two resistive sensors can be connected to make batteryless
sensing points. In this tag mode, the chip can supply a regulated voltage to
the other components of the application. Adding a battery will enable the use
of the standalone data logging mode. The sensor output data is stored in the
internal 3.5kbits user memory. One can extend the storage capacity by connecting
an external E2PROM to the SPI port. The SPI port can also connect the MLX90129
to a microcontroller which allows more specific applications, like adding actuating
capability or RF transmission.

 RFID Reader Board
The RFID Reader Board is an universal HF frontend
for mobile and stationary 13.56MHz reading devices. The MLX90121 RFID-Transceiver
IC supports all common used standards like ISO/IEC 14443B and ISO/IEC15693.
A serial interface to a free to choose microcontroller is onboard. Therefore
it is easy to implement a fully functional reader.
For software support free ANSI-C code is available.
