Its 108 MHz SPI clock, combined with Quad I/O and QPI interfaces, delivers read throughput that keeps an MCU's execute-in-place (XIP) path fed without wait-state bottlenecks. ## Active lifecycle — no forced redesign on the horizon Infineon lists this part as Active. No last-time-buy notices, no NRND flags. The memory interface supports both SPI Quad I/O and QPI. In Quad I/O mode, the 108 MHz clock yields read throughput for a 64 Mbit firmware image.","metaTitle":"S25FL064LABNFN040 Infineon 64Mbit NOR Flash, 108 MHz SPI","metaDescription":"Infineon S25FL064LABNFN040 64Mbit NOR Flash, SPI Quad I/O/QPI, 108 MHz, -40 to 125°C, 8-USON.
