512 Mbit SPI NOR Flash for code and data storage
It uses a Quad I/O SPI interface that can clock at 80 MHz, giving a practical read throughput that suits firmware shadowing, configuration storage, and data logging in embedded systems.
The 80 MHz clock rate with Quad I/O (four data lines) delivers a theoretical peak of 320 Mbps. In practice, firmware boot times and OTA staging benefit from the faster read speed compared to standard SPI, especially when the MCU or SoC supports Quad I/O directly. If your design uses a single SPI bus shared with other peripherals, the 80 MHz ceiling sets the timing budget for the bus arbitration.
The surface-mount package is suited for reflow assembly; standard MSL handling applies.
For new designs, this means no immediate supply discontinuity to plan around.
