Pack of 5 W25Q128 serial flash memory ICs (models: W25Q128FVSG / 25Q128FVSG / 25Q128 / W25Q128FVSSIG). Each device is supplied in the SOP8 (8pin) package for easy boardlevel mounting and replacement. Key benefits storage density in a compact form: each IC provides 128Mbit (16Mbyte) nonvolatile serial flash memory—useful when you need substantial code or data space without a larger package. Dropin friendly SOP8 package: simplifies replacement and prototyping on existing PCBs or breadboards that accept standard 8pin SOP devices. Reliable, longterm storage: designed for persistent firmware and data retention so your system boots and runs consistently after power cycles. Broad system compatibility: works with common SPIbased host controllers and microcontrollers, making it a practical choice for firmware and resource storage across many embedded platforms. Key attributes Functionality: Serial flash memory IC for program code, configuration, or data storage. Models included: W25Q128FVSG, 25Q128FVSG, 25Q128, W25Q128FVSSIG (equivalent W25Q128 family part numbers). Package: SOP8 (8pin small outline package), suitable for throughhole or surfacemount adapter use. Capacity: 128Mbit (16Mbyte) per IC. Performance: Designed as nonvolatile, density storage for read/write program and data access in embedded systems. Compatibility: Intended for systems using standard SPIcompatible flash devices and common microcontroller interfaces. Typical applications / use cases Firmware storage and updates: Store bootloaders, application firmware, or fieldupgradeable code for microcontrollerbased products and consumer electronics. Embedded systems and IoT devices: Provide program space and resource storage (images, configuration tables, lookup data) in compact devices where board space is limited. and spare parts: damaged or worn flash ICs on development boards, routers, set boxes, or other equipment that uses a W25Q128series SOP8 memory. Additional notes Quantity: 5 pieces of the specified W25Q128 family ICs per . Package type and model numbers are listed exactly as supplied—confirm pinout and footprint compatibility with your board prior to installation.
