W25Q16DVSNIG

Memory IC Overview

The W25Q16DVSNIG is a 16M-bit (2M-byte) Serial Flash memory IC manufactured by Winbond Electronics. It operates on a single 2.7V to 3.6V power supply and supports SPI clock frequencies up to 104MHz, enabling equivalent data rates of 208MHz for Dual I/O and 416MHz for Quad I/O. The device features an array organized into 8,192 programmable pages of 256 bytes each, with erase capabilities at 4KB sector, 32KB block, 64KB block, or chip levels. It includes advanced security features such as hardware write protection, top/bottom block protection, and a 64-bit unique serial number.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI interfaces for high-speed data transfer and execute-in-place operations.
• Provides flexible architecture with uniform 4KB sectors and programmable page sizes for efficient data storage.
• Includes advanced security mechanisms like hardware write protect, OTP protection, and unique device identification.

Memory IC Applications

• Code shadowing to RAM
• Execute in place (XIP) applications
• Storage of voice, text, and data

Memory IC Procurement Notes

Verify the specific package variant against the datasheet, as the SN suffix denotes an SOIC-8 package. Confirm that the required operating temperature range aligns with the -40°C to +85°C specification. Ensure compatibility with the 2.7V to 3.6V supply voltage requirements. Check for any specific ordering suffixes that might indicate different packaging options or lead times.

Memory IC Selection Notes

Select this component when space-constrained systems require non-volatile storage with high performance. It is suitable for applications needing code execution directly from flash via XIP. Consider its low power consumption and wide temperature range for industrial or consumer electronics. Verify that the 16M-bit capacity meets the system's storage needs without excessive cost.
