CC3220SF-LAUNCHXL: Execution FLASH Specifications

Stuart Baker

I cannot seem to find the endurance (rated cycles and retention time) or timing (typical/max program/erase cycle) specification for the on-chip execution FLASH in the datasheet. Is it there and I'm just missing it? If it is truly missing, can it be provided?

For customers wishing to use the upper 512K bank of FLASH for an on-chip non-volatile data storage, this is useful information.

Thanks,

Stuart

Hi Stuart,

I found generic flash endurance characteristics are mentioned in the application note below: "A typical serial flash has a data endurance of 100K write cycles per sector and a 20-year data retention. The write endurance and data retention characteristics must be considered by the application developer."

However, it seems exact endurance specs are not included in the datasheet. Let me check on this and update you soon.

Austin,

Thanks for looking into this. To be clear, I'm not asking about the specs on the serial FLASH, these are reasonably well documented. I'm asking about the specs for the on-chip 1MB parallel execution FLASH.

Thanks,
Stuart

Let's discuss offline. I'll marked this closed for now, but I do want to followup once we have more data.
