The 16-SOIC package (0.295-inch body width, 7.50 mm) is a common footprint for code-storage Flash in embedded systems. Page program time is 3 ms typical; word program time is 5 µs typical. ## Obsolete – Plan for Last-Time Buy or Replacement Infineon lists the S25FL129P0XMFI003 as Obsolete. No official successor part number is provided in the available records. For existing BOM lines, a last-time buy or a pin-compatible alternative from the same FL-P family should be evaluated immediately. The base product number S25FL129 covers multiple speed and temperature variants in the 16-SOIC package. Cross-referencing the full order code against current Infineon Flash selector guides is recommended to identify a drop-in replacement with equivalent density, interface, and timing. Because the part is obsolete, standard distributor stock is depleted. Sourcing through independent channels is the primary route. The 16-SOIC package is moisture-sensitive; verify the MSL level before opening the reel.","metaTitle":"S25FL129P0XMFI003 Infineon 128 Mbit NOR Flash – Obsolete","metaDescription":"S25FL129P0XMFI003 Infineon FL-P series 128 Mbit SPI Quad I/O NOR Flash, 104 MHz, 16-SOIC.
