GD25Q64CFIG

Memory IC Overview

The GD25Q64CFIGR is a 64 Mbit (8M x 8) NOR flash memory manufactured by GigaDevice. It operates on a single 2.7 V to 3.6 V power supply and supports Standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 120 MHz. The device features uniform 4 K-byte sectors and 32/64 K-byte blocks. It is housed in a 16-lead SOP package (300 mil width) and is rated for industrial temperatures ranging from -40 °C to +85 °C.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface modes for flexible data transfer rates.
• Provides hardware and software write protection mechanisms including top/bottom block protection.
• Includes advanced security features such as unique identification registers and one-time programmable lock bits.
• Enables execute-in-place operation for direct code execution from the memory.

Memory IC Applications

• Storage of firmware and boot code for microcontrollers
• Configuration parameter storage in embedded systems
• Data logging applications requiring non-volatile retention

Memory IC Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific suffix matches the required package and temperature grade. Check current lifecycle status as this part may be subject to discontinuation notices. Ensure design compliance with RoHS directives before integration into final products.

Memory IC Selection Notes

Select this component when a 64 Mbit capacity with uniform sector architecture is required. The 16-pin SOP package suits designs needing additional pin isolation or specific footprint constraints compared to smaller packages. Verify that the operating voltage range aligns with the system's power supply rails and that the industrial temperature rating meets environmental requirements.

Memory IC Part Context

This part belongs to the GD25Q64C series of 3.3V uniform sector dual and quad serial flash memories. The 'FIGR' suffix indicates the 16-lead SOP package variant with tape and reel packaging. It shares core electrical specifications with other variants in the family but differs in physical dimensions and shipping format.

Memory IC FAQ

What is the difference between the WP# and HOLD# pins in Quad SPI mode?

When the Quad Enable (QE) bit is set to 1, the WP# and HOLD# pins function as bidirectional I/O pins IO2 and IO3 respectively, enabling quad data transfer instead of their standard control functions.

How is the device ID read using the Quad I/O interface?

The Read Identification command (9FH) can be executed via the Quad I/O interface to retrieve the Manufacturer ID, Joint Device ID, and Unique ID simultaneously across all four data lines.
