2. General Description
The MLX90129 combines a precise analog 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 components than a 13.56MHz tuned
antenna, it becomes an RFID temperature sensor.
For measuring other parameters, one or two resistive
sensors can be connected to create a battery-less sensing
point. The chip also provides a regulated voltage, derived
from the RFID field, that can be used to supply the external
sensing electronics 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 EEPROM to the SPI port.
The SPI port can also connect the MLX90129 to a
microcontroller which allows more specific applications, like
adding actuating capability, LED driving
The MLX90129 has been optimized for low power, low
voltage battery and battery-less applications.
