32 Mbit NOR flash with Quad SPI at 108 MHz
The Infineon S25FL132K0XNFA013 is a 32 Mbit serial NOR flash organized as 4M x 8 bits, using the SPI Quad I/O interface to reach a clock frequency of 108 MHz. This Quad I/O protocol allows four data lines to transfer simultaneously, quadrupling the read throughput over a standard SPI bus — useful for fast boot or code-shadowing in automotive ECUs that need to load firmware into RAM quickly. This temperature grade suits under-hood or cabin-mounted modules where the ambient may reach 85°C but not the full 125°C of Grade 1.
The 8-pin narrow-body SOIC is a common NOR flash package — the same land pattern serves many pin-compatible parts from other vendors, which simplifies second-sourcing or last-time-buy inventory planning. The write cycle time is 3 ms per page or word, which sets the floor for in-application firmware updates. For a 32 Mbit device, a full-chip erase and rewrite will take several seconds at this page-write speed; the firmware update routine should budget this into the system downtime window.
For existing BOM lines that require this exact ordering code, the part is sourced through independent distribution channels — quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement from Infineon is documented, so a board-level qualification of an alternative NOR flash may be needed for new designs.
