The W25Q16JVUXIQ is a high-performance Serial NOR Flash memory IC manufactured by Winbond. It provides 16Mbit (2MB) of non-volatile storage and supports Standard SPI, Dual SPI, and Quad SPI communication interfaces for fast data transfer in embedded systems.

This IC is widely used in:

• BIOS/UEFI firmware storage
• Embedded systems
• IoT devices
• Microcontroller firmware storage
• Industrial automation
• Consumer electronics
• FPGA configuration storage
• Automotive and networking equipment

The device operates from a 2.7V to 3.6V supply and supports clock frequencies up to 133MHz, enabling very fast read operations. It is optimized for low power consumption and compact PCB designs through its ultra-small USON package.
