The S25FL132K0XMFV040 is officially classified as Obsolete by Infineon Technologies, meaning the manufacturer has ceased production and no further last-time-buy windows are open.
32 Mbit NOR Flash with Quad I/O at 108 MHz
The 108 MHz Quad I/O interface delivers a sustained read bandwidth that suits code-shadowing and execute-in-place (XIP) applications where the microcontroller fetches instructions directly from the flash, reducing the need for a large SRAM cache.
8-SOIC footprint and write-cycle timing
The page (word) write cycle time is 3 ms typical — budget this into the firmware update routine; a full 256-byte page program takes 3 ms, and a 64 KB sector erase typically runs 45 ms to 100 ms depending on the die revision.
