MLX90129
13.56MHZ SENSOR TAG / DATALOGGER IC
1 Functional Diagram 2 General Description
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 components than a 13,56MHz
tuned antenna, it becomes an RFID temperature
sensor.
For measuring other physical parameters, one or
two resistive sensors can be connected to make
battery-less sensing point. Also, the chip can
supply a regulated voltage to 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 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.
