GD25LR256EYIGR

Memory IC Overview

The GD25LR256EYIGR is a 256 Mbit SPI NOR Flash memory device manufactured by GigaDevice. It operates within a voltage range of 1.65 V to 2.0 V and supports an industrial temperature range of -40°C to +85°C, with automotive-grade options extending to +105°C or +125°C. The component utilizes WSON-8 packaging (available in 6x5 mm and 8x6 mm variants) and features Single I/O, Quad I/O, QPI, and DTR interface modes. Clock frequencies reach up to 104 MHz for x1/x4 modes and 60 MHz for x4 DTR mode.

Memory IC Feature Summary

• Supports Dual/Quad I/O data transfer modes alongside standard SPI and QPI interfaces for flexible system integration.
• Includes hardware reset and write protect pins to ensure data integrity and operational security.
• Features dedicated security registers equipped with OTP locks for robust code protection.
• Provides a unique identifier for individual device tracking and authentication.

Memory IC Applications

• Industrial control systems requiring reliable non-volatile storage
• Automotive embedded applications meeting AEC-Q100 standards
• Consumer electronics utilizing low-voltage power supplies
• IoT devices needing compact surface-mount packages

Memory IC Procurement Notes

Verify the specific package dimension variant required, as the GD25LR256E series is available in both 6x5 mm and 8x6 mm WSON-8 footprints. Confirm whether the design requires standard industrial (-40°C to +85°C) or extended automotive (-40°C to +105°C/+125°C) temperature ratings. Ensure the Bill of Materials accounts for the correct suffix indicating the specific thermal and mechanical characteristics defined in the official datasheet.

Memory IC Selection Notes

Select this component when a 256 Mbit capacity is needed with a strict 1.65 V to 2.0 V supply constraint. It is suitable for designs requiring high-speed Quad I/O or DTR access modes. Consider alternative models from the GD25Q or GD25L families if a wider 2.7 V to 3.6 V operating voltage range is acceptable or if different package sizes are preferred for the PCB layout.
