I've read on this forum that the M25P series flash parts are software compatible with the same density EPCS parts (and, in fact, have the same pin-out)
I would like to use a M25P16 instead of an EPCS4, primarily because it's a higher density in the same SO8 package; but also because it's significantly cheaper. I noticed that the EPCS16 isn't available as an SO8 (at least on digikey. which only offers them in SO16). Cost difference over an EPCS4 isn't that great, but it's a discontinued part.
I would like to use the remainder of the flash to store program code that won't fit in BRAM (essentially, I want to swap in programs from flash)
Since the pinout is the same, I suppose I could try it and see, but I'm curious to know if anyone has had reportable success replacing an EPCS part with an M25P part - both for configuration and for programming. If it doesn't work, I'll need to either find a source for EPCS16's in SO8 packages, or drop another flash part on the board.
Thanks!
