Memory IC Procurement Notes

Verify the specific suffix 'W' indicates the industrial temperature grade (-40°C to +85°C) and low-voltage range (1.65V-3.6V) compared to standard variants. Confirm the 'I' suffix denotes the industrial rating if applicable to your design requirements. Ensure compatibility with SOP-8 footprint dimensions during PCB layout. Check for RoHS compliance status in the latest datasheet before finalizing procurement specifications.

Memory IC Selection Notes

Select this component when designs require a 2 Mbit capacity with a 1.65 V minimum supply voltage, distinguishing it from standard 2.7 V parts. The 100 MHz clock speed offers sufficient performance for many embedded applications. Consider the SOP-8 package size constraints and industrial temperature range requirements. Verify that the Quad I/O mode meets bandwidth needs without requiring higher-frequency alternatives.

Memory IC Part Context

This part belongs to the GD25WD series of SPI NOR flash memories designed for low-voltage and industrial applications. It shares the 2 Mbit density with other members like the GD25Q20C but differs in voltage range and temperature rating. The GD25WD series targets applications where power efficiency and reliability in harsh environments are critical priorities over maximum speed.

Memory IC Replacement Considerations

GD25Q20CTIGR: Offers similar 2 Mbit capacity and Quad I/O but typically operates at 2.7 V minimum voltage and may have different temperature ratings.
