Page program time is 3 ms typical, word program 5 µs — fast enough for OTA staging if your firmware layer manages the 4 KB and 64 KB erase granularity properly. The 8-WSON package with exposed pad helps pull heat out if you're running continuous reads near the temperature ceiling. That doesn't mean it's gone overnight — it means new-production allocation has stopped, and any remaining factory stock or distributor inventory is the last. If your design is already in production, you need to qualify a replacement or secure the remaining supply through independent distribution.","metaTitle":"S25FL129P0XNFI011 128 Mbit SPI NOR Flash, 104 MHz, Obsolete","metaDescription":"S25FL129P0XNFI011 128 Mbit SPI NOR Flash from Cypress FL-P series. 104 MHz Quad I/O, 2.7-3.6 V, -40 to 85 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-P","Package":"Tube","Technology":"FLASH - NOR","Memory Size":"128Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Product Status":"Obsolete","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 ~ 85°C (TA)","Supplier Device Package":"8-WSON (6x8)","Write Cycle Time - Word, Page":"5µs, 3ms"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ccb237c2a38e68c2a9dc926a949a53f9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is S25FL129P0XNFI011 obsolete?","answer":"Yes, the manufacturer lists this part as obsolete. No further production is planned. For existing designs, you'll need to source remaining inventory or move to a replacement.

A common cross-shop candidate within the same Cypress FL-P family is the S25FL129P0XNFI010 — same 128 Mbit density, same Quad I/O interface, same package footprint. Verify pin-compatibility against your layout before ordering. We can also source the original part through independent channels against an RFQ."},{"question":"Where can I buy S25FL129P0XNFI011?","answer":"We source this obsolete part to order through our independent distribution network.
