If you need a drop-in replacement for new designs, the S25FL128S series (same package, same Quad-SPI interface) is the official successor; verify pin compatibility against your layout before committing the BOM. ## 104 MHz Quad-SPI — read throughput and timing margin That is enough to feed a Cortex-M or a small FPGA without a separate parallel NOR. The 3 ms page program time is the bottleneck if you are logging data; for code storage it is irrelevant. ## Package and footprint — 8-WSON with exposed pad This pad is not just for heat — it also provides a low-inductance ground return for the SPI signals.","metaTitle":"Cypress S25FL129P0XNFV000 128 Mbit NOR Flash, 104 MHz","metaDescription":"Cypress S25FL129P0XNFV000 128 Mbit FL-P NOR Flash, SPI Quad I/O, 104 MHz, 8-WSON, -40 to 105°C.
