The S25FS128SAGMFV100 implements both Quad I/O SPI and QPI (Quad Peripheral Interface). In Quad I/O mode, four data lines carry address and data, quadrupling the effective throughput of a single-bit SPI bus. At 133 MHz, the raw read throughput is roughly 66 MB/s — enough to feed a Cortex-M7 or a mid-range FPGA configuration port without stalling. QPI mode further reduces command overhead by sending opcodes over the quad bus, which helps in execute-in-place (XIP) scenarios where every instruction fetch counts. The 105°C ceiling is a step above the commercial 85°C grade, so if your enclosure is sealed or near a heat source, this part gives you the headroom without jumping to a full AEC-Q100 part. No thermal pad to worry about — just a straightforward two-layer layout with a 0.1 µF decoupling cap near the supply pin.","metaTitle":"S25FS128SAGMFV100 128Mbit NOR Flash, 133 MHz, 1.7V–2V","metaDescription":"Cypress/Infineon S25FS128SAGMFV100 FS-S series 128Mbit SPI NOR Flash, 133 MHz clock, 1.7V–2V supply, –40°C to 105°C.
