Hi TI!!!

I need to increase the flash memory through an external 1M flash memory chip. What is the best way to do it?

Thanks very much!

    Hi,

      If you have a parallel flash then you can use the EPI interface in Host Bus mode to interface with a NOR Flash memory. Refer to the EPI chapter in the device datasheet. Note that there is no hardware command write support for Flash memory devices; the Host Bus mode should only be used for Flash memory devices programmed at manufacturing time. If a Flash memory device must be written and does not support a direct programming model, the command mechanism must be performed in software.
