GD25Q64CFIGR

Memory IC Overview

The GD25Q64CFIGR is a 64 Mbit (8M x 8) SPI NOR flash memory manufactured by GigaDevice. It operates on a single 3.3V supply within a voltage range of 2.7 V to 3.6 V. The device supports standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 120 MHz. It features uniform sector architecture with 4 K-byte sectors and 32/64 K-byte blocks. The component is housed in a 16-lead SOP package (SOP16 300mil) and is rated for industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Supports Standard, Dual, and Quad SPI modes for flexible data transfer rates
• Includes hardware and software write protection mechanisms via WP# pin and status register bits
• Features a unique 128-bit ID and three 3K-byte security registers with OTP locks
• Allows Execute In Place (XIP) operation for direct code execution

Memory IC Applications

• Storage of firmware and bootloaders in embedded systems
• Data storage for IoT devices and consumer electronics
• Configuration parameter storage in industrial control units
• Code execution in place (XIP) applications requiring fast read speeds

Memory IC Procurement Notes

Verify the specific ordering suffix FIGR confirms the SOP16 300mil package and tape-and-reel packaging format. Confirm the temperature grade corresponds to the industrial range (-40°C to +85°C). Check current lifecycle status as some variants may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB footprints for the 16-lead SOP package.

Memory IC Selection Notes

Select this part when a 64 Mbit capacity with Quad SPI support is required for high-speed data retrieval. The SOP16 package is suitable for designs where board space allows for larger footprints compared to WSON or SOP8 options. Verify that the system power supply remains within the 2.7 V to 3.6 V range to ensure reliable operation. Consider the 120 MHz clock speed if faster read performance than standard SPI is needed.

Memory IC Part Context

This component belongs to the GD25Q64C series of 3.3V Uniform Sector Dual and Quad Serial Flash memories. It shares core electrical and command set specifications with other packages in the family, such as GD25Q64CSIG (SOP8) and GD25Q64CWIGR (WSON8). The primary distinction lies in the physical package dimensions and lead configuration, while maintaining identical memory organization and interface protocols.

Memory IC FAQ

How does the Quad Enable (QE) bit affect the WP# and HOLD# pins?

When the QE bit is set to 1, the WP# and HOLD# pins function as dedicated data I/O pins (IO2 and IO3), disabling their original hold and write-protect functions.

What is the purpose of the High Performance Mode (HPM)?

High Performance Mode allows the device to operate at higher clock frequencies for read operations, improving data throughput beyond the standard 120 MHz limit under specific load conditions.
