10 Pieces W25Q80BVSIG / 25Q80BVSIG / 25Q80BVSSIG SOP8 Serial Flash IC (25Q80) Key benefits Reliable nonvolatile storage for firmware, configuration and user data — preserves information when power is removed. Compact SOP8 package fits spaceconstrained PCBs and standard adapter boards for easy replacement or upgrades. Multiple compatible partnumber variants (W25Q80BVSIG, 25Q80BVSIG, 25Q80BVSSIG, 25Q80) ensure interchangeability where this family of SPI serial flash is specified. Pack of 10 pieces gives you spare parts for production, repairs or prototyping without repeated ordering. What this chip does and why you need it The W25Q80 / 25Q80 family provides serial (SPI) flash memory used to store boot code, firmware images, calibration or persistent settings. It is commonly used as the primary nonvolatile storage in embedded systems where compact, reliable read/write memory is required. It solves the problem of limited onchip storage by offering an external memory option that is easy to integrate with microcontrollers, systemonmodules, or development boards using standard SPI interfaces. The SOP8 (8pin) form factor makes replacement and layout straightforward for surfacemount assembly or handsoldering on compatible adapter sockets. Key attributes Models included: W25Q80BVSIG, 25Q80BVSIG, 25Q80BVSSIG, 25Q80 (SOP8 footprint). Package: SOP8 (8pin surfacemount package) — compact and industrystandard pinout for SPI flash. Functionality: Serial SPI flash memory for nonvolatile data storage (firmware, configuration, assets). Compatibility: Designed for SPIbased systems and common microcontroller platforms that support external serial flash devices. Compatible with development boards, routers, IoT modules and other electronics that reference the 25Q80 family. Quantity: Pack of 10 identical ICs for bulk use or spare parts. Material / type: Semiconductor flash memory IC (SOP8). Typical use cases Embedded firmware storage: Store bootloaders, firmware images or recovery code for microcontroller or SoCbased products such as IoT devices, consumer electronics, or industrial controllers. Device repairs and upgrades: faulty SPI flash chips on motherboards, routers, multimedia players, or other equipment that uses the 25Q80 family. Prototyping and production: Keep a small stock of identical parts for pcb assembly, firmware testing, and smallbatch manufacturing runs. Why professionals choose this part Standardized part numbers and SOP8 packaging make it straightforward to source, and qualify in existing designs. Packaged in quantities of 10 for convenience during troubleshooting, development and small production runs. Works with industrystandard SPI interfaces and common toolchains used for programming and flashing serial NOR devices. Practical notes Verify your board's pinout and programming voltage requirements against the specific 25Q80 variant on your schematic before installation. Use appropriate programming tools or insystem programming procedures compatible with SPI serial flash memory. Store and handle ICs following standard ESD precautions to avoid device damage.
