What this NOR Flash brings to the board
66 MHz Quad SPI — what it means for read throughput
In QPI mode the address and data phases use four I/O lines, cutting command overhead compared to standard SPI. For a design currently using a single-bit SPI NOR at lower speed, this part eliminates the need to bump up to a parallel NOR or toggle NAND for moderate-density firmware storage.
The exposed pad is electrically connected to the substrate ground; leaving it floating or poorly soldered can degrade thermal performance at elevated ambient.
