8 Mbit SPI NOR Flash in an 8-SOIC — what this part does
The Cypress S25FL208K0RMFI040 is an 8 Mbit SPI NOR Flash memory from the FL2-K series, organized as 1 M x 8 bits. It uses a standard SPI interface with a 76 MHz clock, making it a straightforward choice for code shadowing, configuration storage, or firmware boot in embedded systems.
If you have an existing BOM line using this exact order code, you will need to source it through surplus or independent distribution channels. For new designs, look at current-production SPI NOR Flash from the same or alternative vendors; the 8-SOIC footprint is widely supported.
76 MHz SPI clock and write-cycle timing
The 76 MHz clock frequency supports fast read throughput for execute-in-place (XIP) or high-speed firmware loading. The SPI interface keeps pin count low (standard 8-pin SOIC), saving board space and simplifying layout.
If you need a production-ready alternative for a new BOM, let us know the density, interface, and package requirements; we can recommend a current-production SPI NOR Flash that fits.
