MLX90129: 13.56MHZ SENSOR TAG / DATALOGGER
ICThe MLX90129 combines a precise acquisiti
onchain 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 me
asuring others physical quantities, one or two resistive sensors can be connected to make batteryless sensing point. Also, 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
EEPROMto 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.
The MLX90129 has been optimized for low
power, low voltage battery and battery-less applications.
