I need some Non-volatile data storage within an FXT003, or later after cost reduction within a Q26 module (as used within an FXT003).
Is it possible to battery back up the whole SRAM within the unit ? If so details of power supply please.
It appears possible to use the “A&D service” to store data in FLASH, I need to know the lifetime (number of writes) that the internal FLASH can tolerate. I am currently looking at read-modify-write every 15 minutes which means that the FLASH will get about 130k writes per year…
Is there (even a small amount) of EEPROM available to the user. I need to store trail-of-crumbs diagnostic data away from main memory. I possibly need 32 bytes.
