W25Q80BVSNIG

Memory IC Overview

The W25Q80BVSNIG is an 8M-bit (1M x 8) NOR Flash memory IC manufactured by Winbond Electronics. It features a single 2.5V to 3.6V power supply and supports SPI clock frequencies up to 104MHz, enabling equivalent rates of 208MHz for Dual I/O and 416MHz for Quad I/O. The device utilizes an 8-pin SOIC package with a 150-mil width. It offers flexible architecture with uniform 4KB sectors, 32KB blocks, and 64KB blocks, alongside advanced security features including hardware write protection and a 64-bit unique serial number.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI interfaces for high-speed data transfer
• Provides flexible write protection via software commands and hardware pins
• Enables execute-in-place (XIP) operation through continuous read mode
• Includes a 64-bit unique serial number for device identification

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific package variant against the ordering suffix 'SN' to confirm the 8-pin SOIC 150-mil configuration. Ensure the voltage range requirements align with the 2.5V to 3.6V operating specification. Confirm that the system design accommodates the necessary SPI interface signals and write protection pin configurations as defined in the official datasheet.

Memory IC Selection Notes

Select this component when a compact 8-pin surface-mount solution is required for non-volatile storage. It is suitable for applications demanding high performance through dual or quad SPI modes. Consider the wide temperature range and low power consumption characteristics for embedded environments. Verify compatibility with existing SPI controllers supporting the required instruction sets.
