64Mb Serial NOR Flash (Quad SPI / QPI, 133MHz, SOIC-8 208-mil)
The W25Q64JVSSIQ is a popular 64Mb (8MB) Serial NOR Flash memory featuring Dual and Quad SPI / QPI modes. Designed for high-reliability code storage and fast Execute-in-Place (XiP) operation, it operates up to 133 MHz in Quad I/O mode. It is extensively deployed across networking routers, smart home IoT devices, industrial automation controllers, and consumer electronics. Due to authorized distributor stock depletion and long factory queues, spot market demand remains consistently high.

FAQ
What is the difference between W25Q64JVSSIQ and W25Q64JVSIQ?
The primary difference lies in the package width: SS designates the 208-mil wider SOIC-8 body, whereas S designates the narrower 150-mil SOIC-8 package.
Does this part support high-speed read mode for fast boot-up?
Yes, it supports Quad I/O Read with clock speeds up to 133 MHz, enabling rapid system boot and XiP code execution without caching to RAM.
