Hello,

The downloaded document from https://www.cypress.com/file/444186/download,shows on Pg 17, it's endurance limit of 432 yrs, operating at SCK freq of 40Mhz. These calculations r based on reading 64 byte data sequentially.

If I do random Fast-Read continuously then based on the same calculations the endurance cycles/sec comes to 800,000 (this includes CS disable time of 50nSec) and the yrs to reach this limit falls to ~40

I want to know if I am on the right track or there's something more to it?

Thanks,

Regards,

Sailesh..

Hi Sailesh,

We have a KBA on Endurance limit calculation. I am adding the link below for reference. 

I am not able to follow your calculations for fast read opcode. Can you provide us more details on them for us to better understand them.
