Memory IC Procurement Notes

Verify the specific ordering suffix to confirm the SOP-J8 package type and tape-and-reel packaging format. Confirm RoHS compliance status matches project requirements. Check supply status as this series may have limited availability or be subject to change. Ensure the voltage range aligns with the target system's power supply rails before integration.

Memory IC Selection Notes

Select this component when a 256-kbit capacity is required with I²C interface compatibility. Consider the 1.6 V minimum operating voltage for low-power designs. The SOP-J8 package is suitable for surface-mount assembly. Evaluate the 4 million cycle endurance against application write frequencies. Verify thermal performance within the specified -40°C to +85°C range.

Memory IC Part Context

This part belongs to the BR24G-5 series of I²C bus EEPROMs from Rohm Semiconductor. It shares architectural similarities with other members like the BR24G128FJ-5E2 but offers double the density. The series is designed for general-purpose non-volatile memory applications where space efficiency and low power consumption are priorities.

Memory IC Replacement Considerations

The BR24T256F-W is listed as a similar level replacement with the same pinout but is not recommended for new designs. Verify package dimensions and electrical characteristics carefully when substituting.
