7.2 Digital Controller and memory domains
7.2.1 Digital controller
The main features of the digital part of
MLX90129, called Digital Controller are:
• Slave / Master SPI interface
• RFID interface
• DMA: Direct Memory Access
• Register File controller
• EEPROM controller
• Sensor interface controller
• Clock and Power management
• Core: transactions arbiter and
interrupt manager
The digital controller manages the
transactions between the communication
interfaces, the memories and the sensor. It
allows also a standalone mode with its DMA
unit. All these blocks are described in the
next chapters.
The SPI and RFID communication ways can be used concurrently. The Core transaction arbiter handles the
priorities and the interrupts. It updates some status bits that may be used by the external microcontroller or
the RFID base-station to optimize the communication.
The Digital Controller of the MLX90129 allows the user to do the following tasks, via SPI or RFID:
_ Configure the sensor interface and the communication media.
_ Manage the power consumption, the interrupts, the security items,…
_ Run A/D conversions of the selected sensors.
_ Store (or read) data in the internal or in an external EEPROM.
_ Configure and start a standalone process (sleep – sense – interrupt or store – sleep - …)
_ Get the status of the current process.
All these tasks may be done by simply reading or writing the different memories: EEPROM, registers, ee-
Latches, internal devices. Thus, several address domains are defined to access them in an easy way.
7.2.2 Address domains
Four address domains have been defined to designate the memory and the non-memory devices that act
during the requested transactions:
- EEPROM address domain:
This domain addresses the non-volatile EEPROM. It is used to store the user-defined data and the image of
the Register File that can be automatically downloaded after a power-on. This memory block is energy
independent and can store data even when the MLX90129 is no longer powered.
