GD25LQ80CSIG

Memory IC Overview

The GD25LQ80CSIG is an 8M-bit (1M x 8) SPI NOR Flash memory manufactured by GigaDevice. It operates on a single power supply voltage ranging from 1.65V to 2.1V and supports standard, Dual, and Quad SPI interfaces with a maximum clock frequency of 104MHz. The device features a uniform sector architecture with 4K-byte sectors and 32/64K-byte blocks. It includes advanced security features such as hardware/software write protection, OTP lockable security registers, and a unique ID. The component is housed in an SOP-8 package and is rated for industrial temperature ranges.

Memory IC Procurement Notes

Verify the specific suffix 'SIG' against the manufacturer's official ordering guide to confirm the exact package type (SOP-8 208mil) and tape & reel packaging configuration. Confirm that the industrial temperature range (-40°C to +85°C) aligns with your system requirements. Check current lifecycle status as components may be marked as Not Recommended for New Designs.

Memory IC Selection Notes

Select this component when a 1.8V uniform sector NOR Flash with Quad I/O support is required. Ensure the host controller supports the necessary SPI modes (Standard/Dual/Quad). Verify that the available voltage rails match the 1.65V to 2.1V operating range. Consider the SOP-8 package dimensions for PCB layout constraints.

Memory IC Part Context

This part belongs to the GD25LQ80C series of 1.8V Dual and Quad Serial Flash memories. It is designed to provide high-speed read performance and reliable data retention for embedded applications. The series emphasizes flexibility through multiple interface modes and robust data protection features suitable for various industrial and consumer environments.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the GD25LQ series or other manufacturers' 8M-bit 1.8V Quad SPI NOR flashes. Ensure any substitute matches the 104MHz clock speed and SOP-8 package outline if physical replacement is needed.
