HyperBus vs SPI — interface lock-in
This part uses HyperBus, a high-speed 8-bit parallel interface with separate read/write strobes, not the common SPI found on serial NOR Flash parts like the S25FL256SAGMFV000. HyperBus delivers higher throughput than Quad SPI at 133 MHz, but it requires a host controller with a HyperBus PHY. If your MCU or SoC lacks HyperBus, you cannot drop this in as a direct replacement for a SPI Flash — the interface is fundamentally different.
