• Consumer electronics with limited power budgets

Memory IC Procurement Notes

Verify the exact suffix 'I' corresponds to the industrial temperature range (-40°C to +85°C) and the 'R' indicates reel packaging. Confirm that the SOP-16 package matches your PCB footprint requirements. Ensure the 1.65V to 2.0V voltage domain aligns with your system's power rails before ordering.

Memory IC Selection Notes

Select this component when a low-voltage (1.65V-2.0V) operation is required alongside high-speed read performance up to 166MHz. It is suitable for designs prioritizing low standby current and robust security features like individual block locking. Compare against other GD25LB series variants if different package sizes or voltage ranges are needed.

Memory IC Part Context

This part belongs to the GD25LB series of ultra-low power serial flash memories from GigaDevice. The series targets battery-powered applications requiring extended life and compact form factors. It complements higher voltage options like the GD25Q series by offering optimized power consumption for modern low-voltage SoCs.

Memory IC Replacement Considerations

GD25LB256EWIGR: Same capacity and voltage but WSON-8 package. GD25LT256EFIRR: Similar specs but may differ in specific timing parameters or configuration register defaults; verify electrical characteristics carefully.
