NOR flash retains data without power and supports random-access read, so it fits firmware storage, boot code, and parameter tables where execute-in-place (XIP) is needed. ## Package and board-fit: 8-WSON with exposed pad Housed in an 8-WDFN exposed pad package (8-WSON, 5x6 mm body), the S25FS128SAGNFI100 mounts on the surface. The 1.7 V minimum supply means the part stays within spec even when the 1.8 V rail droops under load — a common condition on battery-powered boards during radio transmission.","metaTitle":"Infineon S25FS128SAGNFI100 NOR Flash, 128Mbit, SPI, 8-WSON","metaDescription":"Infineon S25FS128SAGNFI100 FS-S NOR Flash, 128 Mbit, SPI Quad I/O, 133 MHz, 1.7-2V, 8-WSON, -40 to 85°C.
