256 Mbit NOR Flash with Quad-SPI — density and throughput for firmware and data logging
It uses a SPI Quad I/O and QPI interface running at 66 MHz, which gives you four times the read throughput of a standard SPI bus — useful for fast boot, execute-in-place, or over-the-air update staging without waiting on a serial bottleneck.
Infineon lists this part as Active. That means no last-time-buy clock is running, and the part is eligible for new-design qualification.
