What are recommended SPIFI boot flashes ? Most of the ones from original documentation are obsolete or EOL.
I have to change my S25FL064P ( EOL) to new type. I wanted to take S25FL064L which close, but not exactly identical.
It will not be on ROM known types ( different id), so the boot will be slower ( 18MHz instead of 32MHz),
Besides there are no compatible packages - most new ones are BGA, soics are hard to get. So there will be no backup option in case of failure.
Maybe somebody ( especially from NXP) has a "known-working" list of the newest generations of NOR flashes ?
Hi Jaroslaw Karwik,

Look for example on Spansion ( my current selection):
Spansion | S25FL032P, S25FL064P, S25FL128S, S25FL256S, S25FL256S, S25FL129P, S25FL004K, S25FL008K S25FL016K, S25FL032K, S25FL064K, S25FL116K, S25FL132K, S25FL164K,S25FL127S |
All ***P and ***K are obsolete/last buy/EOL ( old 90nm technology) . Only ***S are recommended for new design.
The smallest ***S is 128MBit - well, I do not need that much and it costs.
Micron | M25PX80, M25PX16, M25PX32, M25PX64, M25P10, M25P16, M25P32, M25P64, M25P80 |
Its even worse with Micron - seems that all M25P* are obsolete.
So that is why I asked. In worst case I will be forced to take S25FL128S - unless I find something better.
