128 Mbit NOR Flash for serial-boot and firmware storage
It communicates over a SPI interface with Quad I/O and QPI support, clocking at up to 133 MHz.
The 133 MHz clock rate with Quad I/O gives an effective read throughput well beyond a standard SPI part. For a firmware-over-the-air staging area or a high-speed boot image, this part keeps the CPU fed without stalling on flash access. The QPI mode reduces command overhead further, which matters when the host controller has limited instruction cache.
Housed in a 24-ball BGA measuring 6x8 mm, this is a surface-mount part.
That means no last-time-buy pressure and no forced redesign for the foreseeable future.
