Memory IC Procurement Notes

Verify the specific suffix 'WTR' indicates tape and reel packaging when ordering. Confirm RoHS compliance status matches project requirements. Check for obsolescence notices as some variants may be not recommended for new designs. Ensure the 8-MSOP package dimensions fit the PCB footprint constraints. Validate the operating temperature range against environmental conditions.

Memory IC Selection Notes

Select this component for applications requiring small form factor memory with I²C compatibility. Consider the 32-kbit capacity for moderate data storage needs. Evaluate the 400 kHz speed against system bus requirements. Compare power consumption metrics with other EEPROM families if battery life is critical. Verify pinout compatibility with existing circuit designs.

Memory IC Part Context

This part belongs to the BR24S series of low-power serial EEPROMs from ROHM. It shares architectural similarities with the BR24T and BR24G series but offers specific performance characteristics tailored for general-purpose memory applications. The MSOP-8 package provides a compact solution for space-constrained designs.
