Question

Maximum NVM write cycles for the STUSB4500

My application makes use of 4 different PDOs but the STUSB4500 can only store 3, to get around this I reprogram the NVM whenever I need access to the fourth. I'm keeping a counter for the number of rewrites so that I can issue a warning when I approach the safe limit. I'd like to know what lifespan I should expect for the NVM in the chip, this topic here is the only reference I can find which states "few thousand" cycles.

If possible I'd like some more clarity on this number, as for example the difference between 1000 and 2000 would double the lifespan of my device
