W25Q64 FLASH Storage Module SPI Interface 8Mbyte

The W25Q64 FLASH Storage Module SPI Interface 8Mbyte delivers compact, low-power external storage ideal for embedded projects and IoT devices — perfect for reliable code and data storage. SKU: MOD-146.

• Key benefits: Adds 8 MByte non-volatile storage without redesigning your board, speeds boot and firmware updates, and preserves logs and media even after power loss.
• Performance you can use: High SPI clock support for fast transfers and support for Dual/Quad SPI modes lets controllers execute code directly (XIP) or quickly shadow code into RAM for faster startup.
• Power and space efficient: Operates from a 2.7—3.6 V supply with very low standby current, making it suitable for battery-powered and space-constrained designs.
• Developer friendly: Standard SPI pinout and wide library support (Arduino, STM32, common SPImemory libraries) make integration and prototyping fast.

Use cases include firmware storage and boot code shadowing, data logging (telemetry, GPS, sensor history), audio/text asset storage, and expanding legacy controllers with external memory. The module's compact module size and industry-standard interface make it ideal for prototypes, production runs and repair/upgrades.

Technical note: This product is sold as SKU MOD-146 and implements the W25Q64 family (64 Mbit / 8 MByte) serial NOR flash with SPI interface, typical clock up to 104 MHz (higher Dual/Quad modes available on some variants), operating voltage 2.7—3.6 V, low-power standby behavior and standard SPI signals (CS, CLK, MOSI, MISO, VCC, GND). Integration tips: use proper pull-ups on CS/IO lines, respect voltage levels for MCU compatibility, and consider filesystem (LittleFS/FAT) or direct flat addressing depending on your application.
