The S25FL204K0TMFI011: This part is officially marked Obsolete by Infineon. No last-time-buy window remains open. For BOM lines that still call out this order code, supply runs through independent distribution — we source and quote to order against an RFQ.
The SPI interface operates at 85 MHz. This is adequate for code shadowing or firmware updates in a 4Mbit device.
No official successor is listed by Infineon. A pin-compatible alternative in the same 8-SOIC footprint and 4Mbit SPI NOR class would need to be evaluated against the supply voltage and clock timing. We can source the original part to order against an RFQ.
It operates on a 2.7V to 3.6V supply and uses the standard SPI interface. The 8-SOIC pinout follows the industry convention for SPI NOR Flash; the datasheet covers the full pin assignment.
