MLX90129
13.56MHZ SENSOR TAG / DATALOGGER IC
10 Application Information
1. RFID temperature sensor tag
The MLX90129 may be used as a 13.56
MHz sensor transponder. The LC
antenna is easy to implement and to
tune thanks to the integrated
programmable capacitance. The internal
sensor allows monitoring the
temperature
without
external
component.
2. RFID multi sensors tag
Thanks to the multi sensor interface of
the MLX90129, two differential sensors
can be added. In this configuration 3
sensor values can be read by RFID.
3. Data logger
The MLX90129 may be used in a
standalone way as a data logger. The
data may be stored in the internal
EEPROM or in an external serial SPI
EEPROM. Using the automatic logging
mode, the MLX91029 wakes-up each
programmed time period, converts the
sensor data and stores it in the selected
memory. This process may be hold or
stopped by an external SPI master
(microcontroller,…) or a RFID base-
station. The data stored in EEPROM
may be read via RFID.
