GD25Q64CSIGR

Memory IC Overview

The GD25Q64CSIGR 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 a maximum clock frequency of 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 128-bit ID. The component is housed in an 8-SOP package and is designed for industrial temperature ranges.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates up to 480Mbits/s
• Provides software and hardware write protection mechanisms including top/bottom block protection
• Includes three 1024-byte security registers with one-time programmable lock bits
• Features a unique 128-bit serial number for individual device identification

Memory IC Applications

• Storing firmware and boot code for microcontrollers
• Embedded systems requiring execute-in-place (XIP) operation
• Industrial control applications needing reliable non-volatile storage
• Consumer electronics and IoT devices

Memory IC Procurement Notes

Verify the specific suffix 'R' indicates reel packaging when sourcing. Confirm the 'I' designation aligns with required industrial temperature specifications. Ensure compatibility with existing PCB footprints for the SOP-8 package. Check for RoHS compliance documentation if required by project standards. Validate that the 120MHz clock speed meets system timing requirements.

Memory IC Selection Notes

Select this component for designs requiring high-speed Quad SPI access and robust data protection. Consider the 8-SOP package size for space-constrained layouts. Evaluate the need for hardware write protection via the WP# pin. Ensure the voltage range matches the system's power supply rails. Review the command set for compatibility with existing firmware drivers.

Memory IC Part Context

This part belongs to the GD25Q64C series of 3.3V Uniform Sector Dual and Quad Serial Flash memories. It is part of GigaDevice's broader portfolio of SPI NOR flash solutions. The series is designed for high performance and reliability in various embedded applications. Other variants in the family may differ in capacity or package type.

Memory IC Replacement Considerations

GD25Q64CSIG is a tube-packaged variant of the same electrical specification. Cross-reference with other 64M-bit SPI NOR flashes from different manufacturers if supply constraints exist, ensuring pinout and command set compatibility.
