TPS65987D: The minimum requirement for SPI flash for non-Thunderbolt application

Guru 29720 points
Part Number: TPS65987D

Hi Team,

I believe minimum requirement for SPI flash for non-Thunderbolt application is the following.
Is my understanding correct?

- The flash memory IC must support 12 MHz SPI clock frequency
- The size of the flash must be at least 64 KB
- The minimum erasable sector size of the flash must be 4 KB

It seems 8Mbit is required for Thunderbolt application but I would like to confirm for non-Thunderbolt application.
