The W25Q32FV (32M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins, and power. This small SMD IC series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data.
The W25Q32FV operates on a single 2.7V to 3.6V power supply with current consumption as low as 4mA active and 1µA for power-down. We recommend using this IC with the SparkFun Qwiic Micro to expand its memory capabilities.
Jargon buster
Plain-language definitions for the technical terms used above.
- Flash memory
- Non-volatile memory that keeps stored data even when power is removed. In this sensor, it matters because enrolled fingerprint templates can remain saved after the project is turned off.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
