That clock rate translates to a read throughput around 66 MB/s in quad mode — enough to feed a high-end MCU or FPGA configuration engine without stalling. At 133 MHz in quad-I/O mode, the S25FL256SAGMFI000 can sustain a read throughput that keeps a Cortex-M7 or a mid-range FPGA configuration controller fed without wait states. The SPI interface is standard — any MCU with a quad-SPI peripheral can drive it. The 256 Mbit density (organized as 32M x 8) gives you 32 MB of code or data storage, which is a common size for firmware images with OTA staging, bootloaders, and file-system partitions. The erase granularity (typically 4 KB and 64 KB sectors on this family) matters when you size the OTA staging area — the smaller sector size reduces write amplification for frequent small updates. The FL-S series is Infineon's mainstream NOR Flash family, and this density and package variant is widely stocked across the independent distribution channel. ## Package and rework — 16-SOIC wide, hot-air friendly The leads are on a 1.27 mm pitch, which is easy to hand-solder or reflow with a hot-air station. The chamfered end marks pin 1 clearly — no orientation guesswork. The wide body also gives the part decent thermal mass; it does not heat-soak as fast as a tiny QFN, which is a plus when you are reworking a board with a preheater.","metaTitle":"S25FL256SAGMFI000 256Mbit NOR Flash, 133 MHz SPI, 16-SOIC","metaDescription":"Infineon S25FL256SAGMFI000 256Mbit FL-S NOR Flash, 133 MHz quad-SPI, 2.7V–3.6V, -40°C to 85°C, 16-SOIC.","metaKeywords":null},"attributes":{"series":"FL-S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-S","Package":"Tray","Technology":"FLASH - NOR","Memory Size":"256Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL256","Memory Organization":"32M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-SOIC","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8400","priceTiers":[{"qty":1,"price":"$5.84000","currency":"USD"},{"qty":10,"price":"$5.32700","currency":"USD"},{"qty":25,"price":"$5.22480","currency":"USD"},{"qty":40,"price":"$5.18700","currency":"USD"},{"qty":80,"price":"$4.65438","currency":"USD"},{"qty":240,"price":"$4.63692","currency":"USD"},{"qty":480,"price":"$4.34585","currency":"USD"},{"qty":960,"price":"$4.16247","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL256SAGMFI000/alternatives.json"},"ai":{"faq":[{"question":"What is the max SPI clock frequency of S25FL256SAGMFI000?","answer":"The maximum SPI clock frequency is 133 MHz.
