W25Q16DVDAIG

Memory IC Overview

The W25Q16DVDAIG is a 16M-bit (2M-byte) Serial Flash memory device manufactured by Winbond Electronics. It supports standard, Dual, and Quad SPI interfaces with clock frequencies up to 104MHz. The device operates on a single 2.7V to 3.6V power supply and features an array organized into 8,192 programmable pages of 256 bytes each. It includes flexible architecture with 4KB sectors, advanced security features, and a 64-bit Unique ID.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI operations for high-performance data transfer
• Features efficient Continuous Read Mode allowing true Execute In Place (XIP) operation
• Includes hardware and software write protection with top/bottom block control
• Provides a 64-bit Unique Serial Number for individual device identification

Memory IC Applications

• Code shadowing to RAM
• Executing code directly from Dual/Quad SPI (XIP)
• Storing voice, text, and data in space-constrained systems

Memory IC Procurement Notes

Verify the package type associated with the DAIG suffix against official documentation, as 'DA' typically denotes PDIP while 'I' indicates industrial temperature range. Confirm availability through authorized distributors as specific suffix combinations may have limited stock or require special ordering. Ensure compatibility with system voltage and interface requirements before procurement.

Memory IC Selection Notes

Select this component when a 16M-bit capacity is required with support for Quad SPI operations. It is suitable for applications needing low power consumption and wide temperature ranges. Consider the available packaging options such as SOIC, WSON, or TFBGA based on board space constraints. Verify that the system controller supports the necessary SPI modes and instructions for optimal performance.

Memory IC Part Context

The W25Q16DV belongs to the SpiFlash family, offering flexibility beyond ordinary Serial Flash devices. It is designed for systems with limited space, pins, and power. The device maintains compatibility with standard SPI protocols while adding Dual and Quad I/O capabilities for enhanced throughput. It is part of a broader series ranging from 8Mb to 64Mb densities.
