The 256 Mbit density organised as 32M x 8 gives the firmware map room for a bootloader, two application images for OTA fallback, and a config sector, all on a single NOR die without external paging. ## Quad I/O throughput at 133 MHz The SPI Quad I/O interface clocks at 133 MHz, delivering a sustained read throughput of 532 Mbit/s in quad-output mode — enough to feed a Cortex-M7 executing XIP without wait-state penalties on the instruction bus. The QPI protocol mode reduces the command overhead to a single byte, lowering the bus turnaround latency for random-access reads common in boot and parameter-table lookups. ## Active lifecycle and sourcing Sourced through authorized distribution; availability and current pricing confirmed against the BOM quantity at RFQ time.","metaTitle":"S25FL256LAGMFB003 Infineon 256Mbit SPI NOR Flash, 133 MHz","metaDescription":"S25FL256LAGMFB003 Infineon 256Mbit SPI NOR flash, AEC-Q100, 133 MHz Quad I/O, 2.7-3.6V, -40 to 105°C, 16-SOIC.
