GD25Q64CPIG

Memory IC Overview

The GD25Q64CPIG is a 64M-bit (8M x 8) 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 and 3x1024-byte security registers. The component is housed in an 8-DIP package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI modes for flexible data transfer rates up to 480Mbits/s.
• Provides comprehensive data protection via software block protect bits and hardware WP# pin control.
• Includes three 1024-byte security registers with one-time programmable lock bits for permanent protection.
• Enables execute-in-place (XIP) operation for direct code execution from the memory.

Memory IC Applications

• Storing firmware and bootloaders for microcontrollers
• Code storage for IoT devices and embedded systems
• Configuration parameter storage in consumer electronics
• Data logging applications requiring high reliability

Memory IC Procurement Notes

Verify the specific suffix 'PIG' corresponds to the 8-DIP package and industrial temperature range (-40°C to +85°C). Confirm that the ordering information matches the required lead times and availability status directly from the manufacturer or authorized distributors. Ensure compliance with RoHS directives and moisture sensitivity levels specified in the datasheet before integration into production designs.

Memory IC Selection Notes

Select this component when a DIP-8 package is required for prototyping or through-hole assembly instead of surface-mount options. It is suitable for applications needing robust data retention and write protection mechanisms. Consider the 120MHz speed limit for high-throughput requirements. Verify voltage compatibility within the 2.7V to 3.6V range for the target system design.

Memory IC Part Context

This part belongs to the GD25Q64C series of 3.3V Uniform Sector Dual and Quad Serial Flash memories. The series offers various package options including SOP8, WSON8, TFBGA-24, and DIP8. The GD25Q64CPIG specifically denotes the DIP-8 variant designed for industrial temperature ranges, providing a reliable non-volatile storage solution within the broader GigaDevice NOR flash portfolio.

Memory IC Replacement Considerations

Check for compatible alternatives within the GD25Q64 family that offer different packages if DIP is unavailable. Verify pinout compatibility with other 64Mbit SPI NOR flashes from manufacturers like Winbond or Macronix, ensuring interface and command set alignment before substitution.

Memory IC FAQ

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

In Quad SPI mode, when the Quad Enable (QE) bit is set to 1, the WP# pin functions as IO2 and the HOLD# pin functions as IO3, becoming bidirectional data I/O pins rather than their dedicated control functions.

How is the security register protected from accidental modification?

The security registers are protected by LB3, LB2, and LB1 bits in the status register. These are one-time programmable bits; once set to 1, the corresponding security registers become read-only permanently.
