GD25LQ256DWAGY

Memory IC Overview

The GD25LQ256DWAGY is a 256 Mbit NOR flash memory IC manufactured by GigaDevice. It features an SPI interface with Quad I/O and QPI support, operating at a maximum clock frequency of 104 MHz. The device utilizes an 8-WSON (5x6 mm) package and supports a supply voltage range of 1.65 V to 2 V. It offers a storage organization of 32 M x 8 bits and operates within an industrial temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Supports SPI, Quad I/O, and QPI interfaces for flexible data transfer modes.
• Operates on a low voltage supply range of 1.65 V to 2 V.
• Provides extended industrial temperature operation up to +125°C.
• Utilizes a compact 8-WSON surface-mount package.

Memory IC Applications

• Industrial embedded systems requiring wide temperature tolerance
• Consumer electronics utilizing low-voltage power supplies
• Firmware storage in compact IoT devices

Memory IC Procurement Notes

Verify the specific suffix 'WAGY' against the official datasheet to confirm the exact package dimensions and tape-and-reel specifications. Confirm the current lifecycle status, as availability may vary. Ensure the design accommodates the 1.65 V to 2 V supply requirement and the 104 MHz maximum clock speed constraints.

Memory IC Selection Notes

Select this component when a 256 Mbit capacity is required in a small 8-WSON footprint. It is suitable for designs constrained by low voltage rails between 1.65 V and 2 V. The extended high-temperature rating makes it appropriate for harsh industrial environments where standard commercial grade parts may fail.

Memory IC Part Context

This part belongs to the GD25LQ series of SPI NOR flash memories from GigaDevice. The series is characterized by its low-voltage operation and support for multiple interface modes including Quad I/O and QPI. The 256 Mbit density provides substantial storage for code execution and data retention in space-constrained applications.

Memory IC Replacement Considerations

Check for direct pin-compatible alternatives within the GD25LQ family that may offer different packaging or lifecycle statuses. Verify if higher-speed variants like the GD25LQ256DWIGR are acceptable if the 104 MHz limit is not critical.
