On our product using the NXP LPC4350FET256, we are currently using a 150 mil SOIC-8 SPIFI Flash chip: Winbond W25Q80BVSNIG (8Mbit). This chip is going end of life and we would like to find an alternative with the same package but larger memory size - at least 16Mbit but preferably 32 Mbit. I can’t find a part that matches the package size on the standard list in the user manual for the LPC4350. Is there a more extensive list available than what’s in the user manual, or does anyone have any recommendations?

From research I am looking at the following possibilities, do you know if any of these are compatible with the boot ROM code. I am hoping that they will boot properly and be configured to operate at the highest speed without any further configuration after boot ROM startup.

Spansion
S25FL132K0XMFI043(32Mbit)
S25FL116K0XMFI043(16Mbit)

Winbond
W25Q16DVSNIG(16Mbit)

Macronix
MX25U1635EM1I-10G(16Mbit)

I currently am not able to confirm that the following will work, however, the boot-ROM was modified so they should officially be bootable. The prices of these are quite low.

Micron makes two different sizes:
Narrow:
N25Q032ESC
Wide:
N25Q032ESE
