8.6 SPI and Serial memory
An external serial memory of type FRAM is available to store the current UIDs of the RFID transponders
inventoried in the field, in stand alone mode. It is accessed by the microcontroller through the SPI serial
interface (MISO, MOSI and SCK). The FRAM has to be selected using the signal EEPROM_CS.

Important note: The stand alone application is not implemented in the version 1.0 of the firmware but could
be in the next revision. Please contact your Melexis representative to get the latest revision of the firmware.
The description of the change in the revision list of the firmware will give an indication if the function has been
implemented.
The connector J1 is used to program the microcontroller with the application firmware.
