It communicates over a Quad I/O SPI interface at up to 80 MHz, which gives the host controller a practical read throughput that supports execute-in-place code or fast firmware staging without a parallel bus.
The 24-TBGA package (24-BGA, 8x6 mm body) is a surface-mount footprint that requires careful PCB layout for the SPI signal routing and decoupling. The supplier device package is 24-BGA (8x6).
