MLX90129
13.56MHZ SENSOR TAG / DATALOGGER IC
- Register File address domain:
This memory domain is used to store the current configuration information of all internal MLX90129 devices
(Sensor interface, Power management …). This memory is energy-dependent and must be updated each
time the MLX90129 is turned-on.
- Internal Devices address domain:
This domain allows accessing the registers linked to the so-called internal devices like the ADC buffers, the
status words of the Core Transaction Arbiter and the EE-Latches. They may be accessed with the
appropriate SPI / RFID commands including its address. The difference with the Register File is the fact that
they are not copied from the EEPROM at the start-up and they may be used during the requested
transaction.
- External memory address domain:
This domain addresses the external memory which can be connected to the MLX90129, using the SPI in
master mode.
