Is it reliable to use S25FL512S QSPI NOR Flash (FL-S; MicroBit Eclipse Architecture) for Application Code Storage in Embedded System? Or such QSPI NOR flash are recommended for data storage only?

According to my knowledge, some years ago both SPI and Parallel NOR flash were available without ECC and NAND flash were available with on-die-ECC. Now I see that QSPI NOR flash is also available with ECC. So I think ECC is required where bit flip can occur. Therefore, I want ask if I need 100% reliable flash memory for application code storage, should I prefer SPI NOR flash without ECC (FL-K; Floating Gate Technology) or QSPI NOR flash with ECC (FL-S; MicroBit Eclipse) Technology? And similarly, is it safe to use FL-P MicroBit architecture NOR flash for application code storage purpose?

Hello,

The S25FL512S (65nM MirrorBit process technology) aswell as the Semper S25HL512T are both ideal for embedded applications requiring code storage, and both devices have ECC.  The S25FL512S and Semper S25HL512T are available and currently in production through 2024.
