I would like to complain about the ease with which you move from "Recommend for new design" to "last time you buy" and I refer to the ADSP-BF518BSWZ4F16 vs device!
This is the second time it goes out of date!
In the world there are not only large companies but also a myriad of small entities that live on small projects.
Thinking only of its shareholders can not always be convenient.
I have invested many years in your products and unfortunately I have made a bad investment.
The integrated flash die resident on the ADSP-BF514F16 and ADSP-BF518F16 products was discontinued by the vendor without a compatible replacement, resulting in the unfortunate and rare situation where ADI can unexpectedly no longer produce the products featuring it. Typically, processors remain in production for 15+ years, but this is simply not possible under these extenuating circumstances. As an alternative, ADI recommends the pin-compatible ADSP-BF514 and ADSP-BF518 with an external SPI flash for designs that can support such a configuration and apologizes for this unplanned situation.
