GD25Q80CSIG

Memory IC Overview

The GD25Q80CSIG is an 8M-bit (1M 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 4K-byte sectors and 32/64K-byte blocks, housed in an 8-SOP package. It provides hardware and software write protection, including top/bottom block protection, and includes a 128-bit unique ID.

Memory IC Feature Summary

• Supports standard, dual, and quad serial peripheral interface operations for flexible data transfer rates.
• Features uniform sector architecture allowing precise software-defined memory protection zones.
• Includes advanced security mechanisms such as a 128-bit unique identifier and one-time programmable security registers.

Memory IC Applications

• Firmware storage for microcontrollers and system-on-chip devices
• Code execution in place (XIP) applications
• Data logging and configuration parameter storage

Memory IC Procurement Notes

Verify the specific suffix 'SIG' corresponds to the SOP-8 208mil package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status and moisture sensitivity level requirements during handling. Check current manufacturer lifecycle status as this component may be designated as Not Recommended for New Designs.

Memory IC Selection Notes

Select this part when a uniform sector layout is required for consistent erase sizes across the memory array. Ensure the host controller supports the necessary SPI modes for Dual or Quad I/O if high-speed read performance is needed. Verify that the operating voltage range aligns with the system's 2.7V to 3.6V supply rails.

Memory IC Part Context

This component belongs to the GD25Q80C series of 3.3V uniform sector serial flash memories. It is designed for applications requiring reliable non-volatile storage with flexible protection schemes. The series supports various package options, with the SIG suffix specifically denoting the surface-mount SOP-8 form factor suitable for industrial environments.

Memory IC FAQ

How does the Quad Enable (QE) bit affect pin functionality?

When the QE bit is set to 1, the WP# and HOLD# pins are reconfigured as dedicated data I/O pins (IO2 and IO3) to support Quad SPI operations.

What is the function of the Hold signal?

The Hold signal pauses serial communication without interrupting ongoing program or erase operations. It requires CS# to remain low and SCLK to be low to activate.
