Memory IC Procurement Notes

Verify current availability status as distribution channels may vary. Confirm RoHS compliance details through official documentation before integration. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate package dimensions against PCB footprint requirements during design phase.

Memory IC Selection Notes

Select this component when 4 Mbit capacity and 104 MHz performance are required in a standard 8-pin package. Consider the 2.3 V to 3.6 V operating range for compatibility with system power rails. Evaluate thermal requirements to ensure operation within the specified -40°C to +105°C range for target environments.

Memory IC Part Context

This part belongs to the IS25LQ series of serial flash memories from ISSI. The series provides cost-effective solutions for embedded storage applications. The JBLE suffix indicates specific packaging and environmental characteristics consistent with the manufacturer's standard product line definitions.

Memory IC Replacement Considerations

Check for direct substitutes within the IS25LQ family such as IS25LQ020 for lower capacity needs. Verify pinout and electrical specifications match before replacing components in existing designs.
