Instead, an external QSPI Flash memory chip is wired up that can provide up to 16 Megabytes (a.k.a 128 Megabits) of memory. It's not as fast as if it were on the microcontroller internal bus but with Quad SPI I\/O and some clever caching by the chip designer, it's pretty effective!\u003c\/p\u003e\n\u003cp\u003eTo make prototyping and designing with QSPI flash a little easier, Adafruit designed these breakouts that convert the wide 8-SOIC packages to a cute 0.3\" wide DIP. We find these handy when testing out different flash sizes, or if we just want to add more storage memory to a project.\u003c\/p\u003e\n\u003cp\u003eThis is the \u003cstrong\u003eW25Q128JVSSIQ\u003c\/strong\u003e, a 3.3V power and logic 128-Megabit \/ 16 Mega-byte chip. Note that the Q at the end means that the Quad Enable bit is permanently set in the status register. If you're using this in QSPI mode, then it'll work right out of the box. If you're using this in SPI mode, the 'hold' and 'write protect' pins don't do anything, so just connect them to 3.3V.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_SPIFlash\" target=\"_blank\"\u003eIn Arduino, we have the Adafruit_SPIFlash library\u003c\/a\u003e that can be used to interface with this chip - but don't forget it's only good for 3.3V logic and power!
