The 133 MHz clock rate on the SPI bus is the figure that determines read bandwidth. In Quad I/O mode the part delivers a sustained read throughput of roughly 66 MB/s, which is enough to feed an ARM Cortex-M7 or a high-end MCU executing code-in-place without stalling. The AEC-Q100 qualification means it has passed the full automotive stress suite (preconditioning, HTOL, TC, HAST, etc.) and is acceptable for under-hood and cabin-domain ECUs. ## Package and footprint — 8-WSON with exposed pad The part is surface-mount only; hand-soldering is possible with a hot-air station and a fine tip, but the exposed pad makes rework trickier than a standard SOIC.","metaTitle":"S25FL128SAGNFA000 128Mbit NOR Flash, AEC-Q100, 133 MHz","metaDescription":"Infineon S25FL128SAGNFA000 128Mbit SPI NOR Flash, AEC-Q100 automotive qualified, 133 MHz clock, 2.7-3.6V, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q100, FL-S","Package":"Tray","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":"Active","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL128","Memory Organization":"16M x 8","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-WSON (6x8)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1500","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL128SAGNFA000/alternatives.json"},"ai":{"faq":[{"question":"Is S25FL128SAGNFA000 equivalent to S25FL128SAGNFI000?","answer":"The two parts are functionally identical — same 128 Mbit density, same 133 MHz Quad-SPI interface, same 8-WSON package.
