GD25Q80CSIGR

Memory IC Overview

The GD25Q80CSIGR is an 8M-bit (1M x 8) SPI NOR flash memory manufactured by GigaDevice. It operates within a voltage range of 2.7V to 3.6V 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 hardware and software write protection, a 128-bit unique ID, and four 256-byte security registers. The component is housed in an 8-lead SOP package and is designated as Not Recommended for New Designs.

Memory IC Feature Summary

• Supports standard, Dual, and Quad Serial Peripheral Interface modes for flexible data transfer rates.
• Provides comprehensive data protection through software block protection and hardware WP# pin control.
• Includes advanced security features such as a unique device identifier and one-time programmable security registers.
• Enables Execute In Place (XIP) operation for direct code execution from the memory.

Memory IC Applications

• Firmware storage for microcontrollers and system-on-chip devices
• Code storage for consumer electronics and IoT applications
• BIOS or boot code storage in embedded systems

Memory IC Procurement Notes

Verify the 'Not Recommended for New Designs' status before finalizing any design implementation. Confirm that the specific SOP-8 package dimensions match the target PCB footprint. Ensure the supply chain source provides valid RoHS compliance documentation. Check for availability of alternative components if long-term supply assurance is required for the project lifecycle.

Memory IC Selection Notes

Select this component only if the application requires 8M-bit capacity with Quad SPI support and operates within the 2.7V to 3.6V range. Consider the 120MHz maximum clock speed for read performance requirements. Evaluate the need for uniform sector erase sizes against the specific firmware update strategy. Verify that the SOP-8 package is suitable for the manufacturing process and thermal constraints of the assembly line.

Memory IC Part Context

This part belongs to the GD25Q80C series of 3.3V Uniform Sector Dual and Quad Serial Flash memories. The 'R' suffix indicates tape and reel packaging, while 'SIG' denotes the SOP-8 package variant. The series is designed for high-reliability applications requiring fast program/erase speeds and robust data retention characteristics typical of GigaDevice's NOR flash portfolio.
