The Cypress S25FL127SABMFV103 is a 128 Mbit NOR Flash memory from the FL-S series, packaged in an 8-SOIC surface-mount footprint. It uses a Quad I/O SPI interface clocked at 108 MHz, offering fast read and program throughput for code shadowing, firmware storage, and parameter retention in embedded systems. The part operates over the industrial temperature range of -40°C to 105°C, making it suitable for outdoor telecom, motor drives, and automotive body electronics where thermal cycling and reliability matter.
Lifecycle and sourcing reality
The manufacturer lists this part as active, but the EOL hot flag indicates the product is on a discontinuation trajectory. For a BOM line that relies on this exact order code, the practical window for last-time-buy orders is narrowing. Sourced and quoted to order against an RFQ through independent distribution — availability and current pricing confirmed at quote time. No official replacement order code is listed in the lifecycle record; for dual-sourcing resilience, a pin-compatible alternative from the same FL-S density family should be evaluated while supply lasts.
