GD25Q80CNIGR

Memory IC Overview

The GD25Q80CNIGR is an 8M-bit (1M x 8) SPI NOR flash memory manufactured by GigaDevice. It operates on a single 3.3V power supply with a voltage range of 2.7V to 3.6V. The device supports standard, dual, and quad SPI interfaces with a maximum clock frequency of 120MHz. It features uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. The component is housed in an 8-lead USON package measuring 3x4mm and is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports standard, dual, and quad SPI communication protocols for flexible data transfer rates.
• Includes hardware and software write protection mechanisms via status register bits and the WP# pin.
• Features advanced security capabilities including unique identification and programmable security registers.
• Provides execute-in-place (XIP) operation for direct code execution from the memory.

Memory IC Applications

• Code storage for microcontrollers and system-on-chip applications
• BIOS and firmware storage in embedded systems
• Data logging and configuration storage in industrial devices

Memory IC Procurement Notes

Verify the specific suffix 'NIGR' corresponds to the USON-8 3x4mm package and tape-and-reel delivery format. Confirm the industrial temperature grade (-40°C to +85°C) matches the design requirements. Check current lifecycle status as NRND (Not Recommended for New Designs) to assess long-term availability risks before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for 8M-bit non-volatile storage. Ensure the host controller supports the necessary SPI modes, including Quad I/O if high-speed read performance is needed. Verify that the 3.3V operating voltage aligns with the system power rails and that the USON-8 footprint fits within the PCB layout constraints.

Memory IC Part Context

This part belongs to the GD25Q80C series of 3.3V uniform sector serial flash memories. It shares architectural similarities with other members of the GD25Q family but is distinguished by its specific package type and thermal rating. The series is designed for cost-effective, high-density code storage solutions in consumer and industrial electronics.

Memory IC Replacement Considerations

GD25Q80CSIGR: Same electrical specifications but in SOP-8 package. GD25Q80CEIGR: Similar capacity and interface in USON-8 package; verify pin compatibility and lifecycle status.
