The GD25Q64 from GigaDevice is a 64M-bit (8M-byte) 3V serial NOR Flash memory supporting standard, dual, and quad SPI interfaces up to 120MHz. It provides reliable, high-density code and data storage for embedded and industrial applications.
Product Overview
The GD25Q64 delivers a low-pin-count, in-system programmable non-volatile memory solution with 65,536 pages of 256 bytes. It is widely adopted for firmware storage, boot loaders, and parameter data in microcontroller and SoC designs where a compact SPI footprint and stable supply are required.
Quad SPI operation boosts read throughput to meet the demands of fast boot and code-shadowing scenarios, while the uniform 4KB sector and 32/64KB block architecture supports flexible over-the-air (OTA) updates and wear-leveling schemes.

FAQ
Q: Is GD25Q64 compatible with other 64M-bit SPI NOR Flash devices?
A: It follows the common SPI Flash command set and 8-pin footprint, but verify voltage, timing, and pinout against your current part before substitution.
Q: What is the typical endurance and retention?
A: Typical endurance is 100,000 program/erase cycles per sector with 20-year data retention; confirm grade-specific values in the manufacturer datasheet.
Q: Can you source hard-to-find or discontinued NOR Flash?
A: Yes. Our alternative-part service helps qualify equivalent devices when a specific density or package is constrained.
