Memory IC Procurement Notes

Verify the specific suffix WE2 against the official datasheet to confirm pinout compatibility and packaging details. Confirm RoHS compliance status through the manufacturer's documentation before integration. Check the current lifecycle status as this part may be discontinued or not recommended for new designs. Ensure the selected distributor provides authentic components with traceable origin to avoid counterfeit risks.

Memory IC Selection Notes

Select this component when a 256-kbit capacity is required with I2C connectivity. The wide voltage range of 1.6 V to 5.5 V allows flexibility in system design. Consider the 8-SSOP-B package size for space-constrained printed circuit board layouts. Verify that the 400 kHz interface speed meets the system's communication requirements.

Memory IC Part Context

This EEPROM belongs to the BR24T series from ROHM Semiconductor, designed for general-purpose memory applications. The series emphasizes low power consumption and robust data retention. The BR24T256FV-WE2 variant specifically utilizes the SSOP-B8 package format, distinguishing it from SOP or TSSOP alternatives within the same density class.

Memory IC Replacement Considerations

BR24T256F-WE2: Same density and interface but in SOP-8 package; verify pinout compatibility.
