Its 133 MHz clock rate delivers a sustained read throughput that keeps a QSPI controller fed without wait-state insertion, provided the PCB trace length and load capacitance are held within the datasheet guidelines. This part targets code-shadow, execute-in-place, and firmware-update storage in systems that need non-volatile memory with fast random-read latency. ## 125 °C operating ceiling — industrial and under-hood deployment Rated for -40 to 125 °C ambient, this flash spans the full industrial temperature range and reaches into automotive under-hood environments where 105 °C or 125 °C is the junction limit. For designs that previously used a 1.8 V NOR part, the 2.7 V minimum rules out direct drop-in; the supply rail must be 3.3 V or a 2.7–3.6 V rail. ## 16-SOIC wide body — footprint check Packaged in a 16-SOIC with 7.50 mm body width — the wide-body variant, not the narrower 3.90 mm or 5.28 mm SOIC footprints common on smaller-density NOR parts. If the board was laid out for a previous-generation 8-pin SOIC or a 16-pin narrow SOIC, the pad pattern will not match.","metaTitle":"S25FL256LAGMFN003 256Mbit NOR Flash, SPI Quad I/O, 133 MHz","metaDescription":"S25FL256LAGMFN003 256Mbit NOR flash from Infineon FL-L series.
