It communicates over a SPI bus with Quad I/O and QPI protocol support, clocked at 133 MHz. The part operates from a 1.7 V to 2 V supply rail. Housed in a 16-pin SOIC wide-body package (7.50 mm body width), it is a surface-mount part suited for reflow assembly and rework. The -40°C to 85°C industrial temperature range covers most embedded, telecom, and IoT edge applications. ## Lifecycle and sourcing posture It remains a current-production line item from Infineon (formerly Cypress). The part is RoHS non-compliant per the listing, so verify your assembly house's exemption policy if the BOM requires full RoHS conformance.","metaTitle":"Cypress S25FS256SAGMFI003 256Mbit NOR Flash","metaDescription":"256Mbit FS-S NOR Flash in 16-SOIC.
