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

connecting an external EEPROM to the SPI port.

The SPI port can also connect the MLX90129 to a

microcontroller

which

allows

specific

applications, like adding actuating capability, LED

driving

The MLX90129 has been optimized for low power,

low voltage battery and battery-less applications.
