Memory IC Procurement Notes

Verify the specific package variant (WSON-8 5x6mm vs 6x5mm) required for your PCB layout before ordering. Confirm the operating temperature grade (-40°C to 105°C vs -40°C to 125°C) matches your environmental specifications. Ensure voltage supply stability within the 1.65V to 2.0V range. Check for RoHS compliance documentation if required by your region. Validate that the supplier provides genuine GigaDevice products to avoid counterfeit risks.

Memory IC Selection Notes

Select this component when low voltage operation (1.65V-2.0V) is mandatory. Choose over standard 3.3V parts if power efficiency is critical. Consider the WSON-8 footprint constraints against available board space. Verify thermal requirements against the specified industrial temperature ranges. Ensure compatibility with existing SPI controllers supporting QPI/DDR modes.

Memory IC Part Context

This part belongs to the GD25LR series, designed for low-voltage applications. It complements the standard GD25Q series by offering lower power consumption at reduced voltages. The LR series targets automotive and industrial sectors where reliability under varying thermal conditions is essential. It shares pinout compatibility with similar capacity devices in the family.

Memory IC Replacement Considerations

GD25B256EWIGR is listed as a parameter-equivalent substitute from Gigadevice Electronics Singapore PTE.LTD. Verify voltage and temperature specifications match exactly before substitution. Other GD25LR variants may serve as alternatives if pin-compatible.
