GD25Q64CQIGR

Memory IC Overview

The GD25Q64CQIGR is a 64M-bit (8M x 8) SPI NOR Flash memory manufactured by GigaDevice. It operates on a single 2.7V to 3.6V power supply and supports Standard, Dual, and Quad SPI interfaces with clock frequencies up to 120MHz. The device features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It includes advanced security features such as hardware/software write protection, 3x1024-byte security registers with OTP locks, and a unique 64-bit ID. The component is designed for industrial temperature ranges (-40°C to +85°C) and offers high endurance with 100,000 program/erase cycles.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates up to 480Mbits/s in Quad I/O mode.
• Provides comprehensive data protection via software block protect bits, hardware WP# pin control, and dedicated security registers with one-time programmable locks.
• Enables Execute In Place (XIP) operation for direct code execution from the flash memory.
• Features a uniform sector architecture allowing granular erasure of 4K-byte sectors or larger 32K/64K-byte blocks.

Memory IC Applications

• Storing firmware and bootloaders for microcontrollers and embedded systems.
• Hosting operating system kernels and application code requiring fast random access.
• Archiving system configuration parameters and user settings in consumer electronics.
• Logging operational data in industrial control and IoT devices.

Memory IC Procurement Notes

Verify the specific package suffix 'QI' corresponds to the required WSON8 (8*6mm) form factor and tape & reel packaging configuration. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with your environmental design specifications. Ensure compatibility with existing SPI controller pins, particularly regarding the Quad Enable (QE) bit requirement for quad-mode operations. Check for any specific revision history updates in the latest datasheet before finalizing the bill of materials.

Memory IC Selection Notes

Select this component when a 64M-bit capacity is required with support for high-speed Quad SPI transfers. It is suitable for designs needing robust write protection mechanisms and unique device identification. Consider this part if space constraints favor the compact WSON8 package over traditional SOP or DIP formats. Ensure the host system can handle the 2.7V-3.6V voltage range and supports the necessary command set for page programming and sector erasing.

Memory IC Part Context

This part belongs to the GD25Q64C series of 3.3V Uniform Sector Dual and Quad Serial Flash memories. The series is characterized by its high performance and security features, targeting diverse design requirements in various applications. It is part of GigaDevice's broader portfolio of SPI NOR flash solutions, which are widely used in embedded systems, consumer electronics, and communications equipment.

Memory IC Replacement Considerations

Check for other GD25Q64C variants with different package suffixes (e.g., CSIG for SOP8) if physical footprint changes are acceptable. Verify functional compatibility with other 64M-bit SPI NOR flashes from manufacturers like Winbond or Macronix, ensuring pinout and command set alignment.
