GD25LQ128DS2GR

Memory IC Overview

The GD25LQ128DS2GR is a 128 Mbit NOR flash memory device manufactured by GigaDevice. It utilizes an SPI interface with a maximum clock frequency of 166 MHz. The component operates within a supply voltage range of 1.65 V to 2 V and supports surface mount installation in an SOP-8 package. It functions reliably across a wide industrial temperature range from -40°C to +105°C.

Memory IC Feature Summary

• Supports high-speed serial peripheral interface operations up to 166 MHz for efficient data transfer.
• Operates on low voltage power supplies ranging from 1.65 V to 2 V for energy efficiency.
• Engineered for robust performance in demanding environments with extended temperature tolerance.

Memory IC Applications

• Industrial control systems requiring reliable code storage
• Consumer electronics utilizing low-voltage architectures
• Embedded applications needing compact surface-mount memory solutions

Memory IC Procurement Notes

Verify the specific suffix 'S2' against official manufacturer documentation to confirm package type and temperature grade alignment. Ensure compatibility with 1.65 V to 2 V power domains during system design. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference datasheet revisions to ensure functional consistency with existing designs.

Memory IC Selection Notes

Select this component when a 128 Mbit capacity is required alongside high-speed 166 MHz operation. The narrow 1.65 V to 2 V voltage window necessitates careful power supply design compared to standard 3V parts. The SOP-8 package offers a balance between pin count and board space. Verify thermal requirements against the -40°C to +105°C operating range.

Memory IC Part Context

This part belongs to the GD25LQ series, which focuses on low-voltage NOR flash technologies. Unlike the GD25F series that typically supports 2.7 V to 3.6 V, the LQ series targets modern low-power applications. The DS2GR suffix indicates specific packaging and tape-and-reel configuration details defined by the manufacturer.

Memory IC Replacement Considerations

GD25LQ128DSIGR shares similar electrical characteristics but may differ in package or temperature specifications. GD25LQ128ESIGR offers 120 MHz speed in SOP-8 but has a limited +85°C temperature range. Verify pinout and command set compatibility before substitution.
