GD25LQ128DSIGR

Memory IC Overview

The GD25LQ128DSIGR is a 128M-bit (16M x 8) NOR flash memory manufactured by GigaDevice. It operates on a single 1.65V to 2.0V power supply and supports Standard, Dual, Quad SPI, and QPI interfaces with a maximum clock frequency of 120MHz. The device features uniform 4K-byte sectors and 32/64K-byte blocks within an 8-SOP package. It includes hardware write protection via the WP# pin, software block protection, and a 128-bit unique ID.

Memory IC Feature Summary

• Supports standard, dual, quad SPI, and QPI modes for flexible data transfer rates up to 480Mbits/s in quad operations.
• Provides advanced security features including hardware write protection via the WP# pin, software block protection, and a 128-bit unique device identifier.
• Features a uniform sector architecture allowing for granular erase operations at 4K-byte sector and 32/64K-byte block levels.

Memory IC Applications

• Code storage for microcontrollers and system-on-chips requiring execute-in-place capabilities.
• Embedded systems needing reliable non-volatile storage for firmware and configuration data.
• Industrial applications operating within the -40°C to +85°C temperature range.

Memory IC Procurement Notes

Verify the specific suffix 'IGR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 1.65V-2.0V voltage range aligns with the target system's power supply rails. Ensure compatibility with the 8-SOP footprint during PCB layout verification.

Memory IC Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside high-speed Quad SPI or QPI interface needs. Consider the uniform sector size for simplified file system management compared to mixed sector devices. Evaluate the 8-SOP package dimensions against available board space constraints.

Memory IC Part Context

This part belongs to the GD25LQ128D series, which offers 128M-bit density in various packages. The 'DSIGR' designation indicates the SOP-8 package variant supplied in reel packaging. It shares core electrical characteristics with other GD25LQ128 variants but differs in physical form factor and shipping container type.

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 repurposed as bidirectional I/O pins IO2 and IO3 to support Quad SPI operations.

What is the default state of the device upon power-up?

Upon power-up, the device defaults to Standard/Dual/Quad SPI mode with the Quad Enable (QE) bit cleared to 0.
