GD25Q64CBIGY

Memory IC Overview

The GD25Q64CBIGY is a 64M-bit (8M x 8) SPI NOR Flash memory manufactured by GigaDevice. It operates on a single 3.3V power supply within the 2.7V to 3.6V range 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, 128-bit unique ID, and three 3KB security registers with OTP locks. The component is designed for industrial temperature ranges (-40°C to +85°C) and offers high endurance of 100,000 program/erase cycles.

Memory IC Procurement Notes

Verify the specific suffix 'BIGY' against official GigaDevice documentation to confirm package type and tape/reel specifications. Confirm that the industrial temperature grade and voltage requirements align with the target design environment. Check current lifecycle status as older variants may be marked as not recommended for new designs.

Memory IC Selection Notes

Select this component when a 64M-bit capacity with uniform sector erase architecture is required. Ensure the host controller supports the necessary SPI modes (Standard/Dual/Quad) for optimal performance. Verify that the available package options meet the PCB space constraints and that the operating voltage range matches the system power rails.

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-speed read capabilities and robust data protection features. It is widely used in applications requiring reliable non-volatile code storage with fast access times and low power consumption profiles.

Memory IC Replacement Considerations

Check for compatible alternatives within the same density class from other manufacturers if supply is constrained. Ensure pin compatibility and command set alignment are verified before substitution.
