Its SPI Quad I/O interface at 104 MHz clock lets the controller read four bits per cycle — a 416 Mbps theoretical throughput that cuts boot time versus a standard SPI part running at the same clock. NOR Flash reads are fast enough to execute code in place (XiP) on many MCUs, so this part suits applications where the processor boots directly from flash without copying to RAM. The 5 µs word write and 3 ms page write cycle times mean field firmware updates are practical but budget the page erase time into the update window. ## Industrial temp grade and supply — where this part fits on the board Housed in a 16-SOIC wide-body (7.50 mm width) package, the part reworks cleanly with a hot-air station — the 0.295-inch body gives enough clearance for a nozzle to reach all pins without cooking adjacent components. Pin 1 is marked with a dot on the package top; the wide SOIC footprint is standard enough that a replacement part from another vendor often lands on the same pads without a board spin. ## Obsolete — sourcing reality for a discontinued NOR Flash For a BOM that already qualifies this footprint and interface, the procurement path is to request a quote against the required quantity. Availability and pricing vary by lot — the part is sourced to order, not held in ready inventory. If the design can tolerate a package change, a current-production NOR Flash in a different package may be a lower-risk long-term option, but that requires a board layout revision.","metaTitle":"Infineon S25FL129P0XMFV003 NOR Flash, 128Mbit, SPI Quad I/O","metaDescription":"Infineon FL-P series 128Mbit NOR Flash, SPI Quad I/O at 104 MHz, 2.7-3.6V, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"title":"S25FL129P0XMFV003","Series":"FL-P","Package":"Tape & Reel (TR)","Technology":"FLASH - NOR","Memory Size":"128Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Clock Frequency":"104 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL129","Memory Organization":"16M x 8","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"16-SOIC","Write Cycle Time - Word, Page":"5µs, 3ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.9734","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ccb237c2a38e68c2a9dc926a949a53f9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does the S25FL129P0XMFV003 work on a 3.3 V nominal rail without extra regulation?","answer":"The 2.7–3.6V supply range covers a 3.3 V nominal rail within normal tolerance. Standard SPI FLASH decoupling — typically 100 nF per VCC pin, placed close to the device — is sufficient. The 2.7 V minimum is the constraint to watch under brown-out; confirm your rail stays above it during all operating states if the application is safety-critical."},{"question":"Does the 3 ms page write cycle time meet typical boot-time budgets for a PLC firmware load?","answer":"A 3 ms page write is routine for SPI NOR flash; the limiting factor for boot time is usually the SPI clock rate and the flash-to-memory-controller transfer mode rather than the write time itself (which applies during programming, not boot-read). If the design uses XIP (execute-in-place) the clock frequency of 104 MHz matters more than the write timing. Confirm the MCU's Quad SPI controller is configured for the 104 MHz interface speed the part supports."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL129P0XMFV003","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL129P0XMFV003 when reusing this data.
