W25Q16JVUXIQ
Overview
The W25Q16JVUXIQ is a 16Mbit (2MB) Serial Flash memory device supporting Standard, Dual, and Quad SPI interfaces. Operating on a 2.7V to 3.6V supply, it achieves high-speed performance with clock frequencies up to 133 MHz and a 6 ns access time. Its ultra-compact 8-USON (2x3mm) package makes it an ideal solution for space-constrained embedded systems requiring non-volatile code or data storage.
Why Choose This Part
The device offers a high-performance Quad SPI mode that significantly increases throughput compared to standard SPI, while the 8-USON package reduces PCB footprint by over 70 percent compared to standard SOIC-8. It features extremely low power consumption, drawing only 1 uA in power-down mode and 10 uA in standby. Security features like a 64-bit unique ID and OTP security registers provide robust options for device authentication and data protection.
Applications
Key Specifications
Getting Started
To interface with this memory, configure your MCU SPI peripheral for Mode 0 or Mode 3. Use the Standard SPI 03h command for basic reading or EBh for high-speed Quad I/O Fast Read, ensuring the USON pad is properly soldered for thermal and ground stability. Developers can utilize the Winbond SFDP (Serial Flash Discoverable Parameters) register to automatically detect memory density and timing characteristics during firmware initialization.
