Minimal Cost configuration - Cyclone IV

I am working on an upgrade to a product that has been in production for ten years now, using a Cyclone II device. The existing FPGA is sufficient to the task, except it is at "end of life" and they ...

If you can use something like an N25Q128A you shouldn't have to worry about the remote update as this uses standard SPI commands.

The next option is to use such a device like the N25Q128A and put a small micro-controller between it and the FPGA?
