Adafruit QSPI DIP Breakout Board - W25Q64 - 64 MBit 8 MByte - W25Q64JVSSIQ

For many modern and powerful chips like the RP2040, ESP32, RT10xx, and STM32 series microcontrollers, designers can save money and reduce the number of chip options by not including built-in Flash memory used to store code and resources. Instead, an external QSPI Flash memory chip is wired up that can provide up to 16 Megabytes (128 Megabits) of memory. Though not as fast as internal bus memory, Quad SPI I/O with caching makes it effective.

This breakout converts the wide 8-SOIC package of the W25Q64JVSSIQ, a 3.3V powered 64-Megabit (8 Megabyte) Flash chip, into a 0.3" wide DIP. It is ideal for prototyping and testing different flash sizes or adding more storage to projects.

The 'Q' in W25Q64JVSSIQ means the Quad Enable bit is permanently set, so it works out of the box in QSPI mode. In SPI mode, the 'hold' and 'write protect' pins do not function and should be connected to 3.3V.

This breakout includes a header for soldering to plug into a breadboard or replace a socketed SPI flash DIP chip.
