The 2.7V to 3.6V supply range mates directly with 3.3V logic families and battery-backed designs. ## Quad I/O — what the 133 MHz bus means for throughput At 133 MHz, the Quad I/O interface delivers an effective data rate of 532 Mbps (four lanes × 133 MHz) in read mode. That is enough to feed a Cortex-M4 or Cortex-M7 core executing from external flash without stalling on instruction fetches, provided the MCU's memory controller supports Quad-SPI with prefetch. For OTA staging, the same throughput cuts the time to write a 16 MB firmware image to under 300 ms. The 128 Mbit density (16 MB) holds a full application image plus a config sector; the 4 KB and 64 KB erase granularity common to NOR Flash lets you update small parameter blocks without rewriting the whole array. ## Package and supply — board-fit notes The 16-SOIC (0.295\", 7.50 mm width) is the wide-body variant — verify the footprint matches your layout. Surface-mount assembly is standard.","metaTitle":"Infineon S25FL128SAGMFIR03 NOR Flash, 128Mbit","metaDescription":"Infineon S25FL128SAGMFIR03 FL-S series NOR Flash, 128 Mbit (16M x 8), SPI Quad I/O, 133 MHz, 2.7V-3.6V, -40°C to 85°C, 16-SOIC.
