Hello all,

I'm thinking to use S29JL032J70TFI320 part in my  for storing configuration files but when I go through the data sheet I found that Chip erase time to be 39 seconds.

Q. Does S29JL032J nor flash really takes 39 seconds for chip erase?

Thank you

Lohith Venugopal

Hello,

39 seconds is the typical chip erase time of the device S29JL032J. We recommend you to implement the data polling algorithm mentioned in the datasheet to know the completion status of program and erase operations.

Thanks and Regards,

Hi

Cypress S29JL032J allows 100K P/E(Program/Erae) cycles.

So, it is defined as a typical specification with chip erase time of 39 seconds.
Therefore, for several erases, chip erase time doesn't require 39 seconds.

Thanks and regards,
