It runs on a 1.7 V to 2 V supply — that narrow window means you cannot drop it onto a 3.3 V SPI bus without a regulator, but it also keeps the active power low in a battery-backed design. The SPI interface supports Quad I/O and QPI modes at up to 133 MHz, which pushes the effective read throughput well past what a single-bit SPI line can manage — useful for shadowing code to RAM on boot or streaming calibration tables. ## Industrial temperature and SOIC footprint Available cut tape or tape-and-reel, which is the usual story for pick-and-place assembly. The SOIC-8 lands on a standard 1.27 mm pitch footprint, so the board layout is straightforward and the decoupling cap sits close to the supply pin without a fight. ## Active lifecycle and compliance baseline That means you can design it into a new BOM today without planning a migration path. The FS-S series is Infineon's current-generation SPI NOR family, so firmware tools and driver support are well-established across MCU ecosystems. No second-source or pin-compatible alternative is recorded on this listing — it is a single-source line, which is normal for a proprietary memory controller interface.","metaTitle":"Infineon S25FS128SAGMFI103 NOR Flash, 128 Mbit, SPI, 8-SOIC","metaDescription":"Infineon S25FS128SAGMFI103 128 Mbit NOR Flash, SPI Quad I/O, 133 MHz, 1.7-2V, -40 to 85°C, 8-SOIC.
