EZ-Host support on the external memory.

Last Updated: September 26, 2011

Can EZ-Host support Flash on the external memory interface?


For the external memory data bus, the hold time on a write to flash memory under hot, low voltage operation can only be guaranteed to 4.5ns. This will violate some flash hold time requirements. Therefore, if flash support is desired, please be sure it does not require a data hold time longer then 4.5ns.
