It stores firmware or calibration data in engine control units, transmission controllers, and ADAS modules where the ambient temperature reaches 105°C. Organised as 32 M x 8 bits, the device supports Quad I/O SPI at a clock frequency of 133 MHz, delivering the read throughput needed for fast boot and over-the-air update windows. ## Temperature grade and supply rail The -40°C to +105°C operating range covers the under-hood automotive temperature band with margin. AEC-Q100 Grade 1 qualification means the part has passed the full suite of reliability stress tests — high-temperature operating life, temperature cycling, and ESD — required for safety-critical and long-life vehicle programs. Housed in an 8-WDFN with exposed pad (8-WSON 6x8 mm), the package requires a thermal pad on the PCB for heat sinking. Supplied in Tape & Reel, the part is compatible with automated pick-and-place assembly for high-volume production lines. For new designs, the part is a current catalogue item with no imminent obsolescence risk. Sourced through independent distribution channels.","metaTitle":"Infineon S25FL256SAGNFB003 NOR Flash, 256Mbit, 133 MHz","metaDescription":"Infineon S25FL256SAGNFB003 256Mbit SPI NOR Flash, 133 MHz clock, -40 to +105°C, AEC-Q100 qualified.
