I have a little wifi chip that doesn't have its own flash storage, but rather connects via SPI. If you wanted to add wifi support to your board using this chip, which is basically a little MCU with WiFi and BT (latest standards, each) would you use a separate flash memory module for this chip or would you slave it to your master MCU somehow?** ** and if the latter, I'd be curious as to how you'd do it. Would it require emulating an SPI flash chip? I think it would.

Hmmm, I would go for SPI into Micro and then process it from there, if the load is high and it could slow down operations then use a separate SPI bus to a memory chip. I would be cautious of trying to emulate SPI on the processor at the risk of slowing down everything. Glenn

This really depends on what it needs the FLASH storage for, frequency of access, storage size, board space, complexity, etc. Knowing what wifi chip you're considering would help but I would probably just stick a small SPI flash chip on there - or at least a footprint for it on a first prototype.
