(time during which the NVM data retains its integrity over time without
rewriting another/same value)?
The AD5270 uses 50-times programmable memory. A charge pump is used to
permanently blow the fuses in memory.
There should be no need to re-write the value but allow 350ms for the initial
write to the memory.
Memory -> array of fuses.
Retention -> Forever and ever
Endurance -> 50-times
