32 Mbit SPI NOR in the FL1-K family
The Infineon S25FL132K0XMFV011 is a 32 Mbit SPI NOR flash from the FL1-K series, organized as 4M x 8 bits. It communicates over a Quad I/O SPI bus at up to 108 MHz, delivering read throughput suitable for execute-in-place (XIP) boot or firmware shadowing in embedded systems.
Where this part sits in the cycle
Infineon lists the S25FL132K0XMFV011 as Obsolete. This part moves through independent surplus channels — quantities are lot-specific and confirmed at RFQ. For a BOM line that already carries this order code, the procurement decision is straightforward: source from the open market against the build quantity. No pin-compatible drop-in from Infineon's current FL1-K portfolio is documented as a direct replacement, so a board spin or qualification cycle would be needed to migrate to an active NOR flash.
Package and board-fit note
The 3 ms page write cycle is typical for this NOR process node. For a firmware update over SPI, budget the write time per page plus the sector erase overhead — the 32 Mbit density means a full-chip erase takes roughly 1–2 seconds at the quad-lane bus rate.
