The W25Q256JVFIQ is a 256M-bit (32MB) Serial NOR Flash memory from Winbond Electronics, packaged in a 16-pin SOIC 300-mil housing (7.50 mm x 10.31 mm x 2.34 mm) with a dedicated /RESET pin. Operating from a single 2.7V to 3.6V supply, it supports Standard SPI, Dual SPI, Quad SPI, QPI, and DTR (Double Transfer Rate) interfaces with clock frequencies up to 133MHz, enabling equivalent rates of 266MHz (Dual) and 532MHz (Quad) for data transfers up to 66MB/s. The memory array is organized into 131,072 programmable pages of 256 bytes each, with 8,192 erasable 4KB sectors and 512 erasable blocks, delivering 100K program-erase cycles per sector and 20-year data retention across -40°C to +85°C operation.
Applications
The W25Q256JVFIQ serves as an ideal storage solution for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP), and storing voice, text, and data across diverse embedded systems. Primary deployments include firmware and boot code storage in embedded controllers, consumer electronics such as smart TVs, tablets, and digital cameras, networking devices including routers and switches requiring fast memory access, industrial control systems operating in harsh -40°C to +85°C environments, and IoT devices with limited space, pins, and power. The 256Mb capacity makes it particularly suitable for storing complete application firmware, operating system images, configuration data, and calibration parameters where high-density non-volatile storage is essential.
