128 Mbit SPI NOR Flash with Quad I/O — what it delivers in the BOM
The Infineon S25FL127SABMFV001 is a 128 Mbit SPI NOR Flash memory from the FL-S series, organised as 16M x 8. It communicates over a Quad I/O SPI interface at up to 108 MHz, which gives the system a practical read throughput well above single-bit SPI — useful for fast boot loading, over-the-air firmware staging, and parameter storage where the controller has a Quad SPI peripheral.
