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 battery-less 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 3.5 kbit 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 micro-controller which allows more specific applications, like adding actuating capability or RF transmission.

The MLX90129 has been optimized for low power, low voltage battery and battery-less applications.
