Housed in a 16-SOIC package (0.295-inch body width, 7.50 mm), the S25FL128SDSMFB001 uses the standard JEDEC SOIC-16 wide footprint. The 1.27 mm pin pitch is hand-solderable and rework-friendly — no hot-air nozzle alignment needed for a rework station. ## Active lifecycle — no end-of-life clock running Infineon lists this part as Active. No LTB notice, no successor announced.","metaTitle":"S25FL128SDSMFB001 – Infineon 128 Mbit NOR Flash","metaDescription":"Infineon FL-S series 128 Mbit NOR Flash, SPI Quad I/O interface, 80 MHz clock, 2.7–3.6 V, -40 to 105°C, 16-SOIC.
