Memory IC Procurement Notes

Verify the specific package suffix matches the required footprint, such as SOP-J8 or TSSOP-B8, as dimensions vary. Confirm the ordering code corresponds to the desired tape and reel quantity. Ensure the component meets AEC-Q100 Grade 1 requirements for the target automotive environment before finalizing procurement.

Memory IC Selection Notes

Select this component when high-speed SPI communication up to 20 MHz is required alongside robust data retention in automotive environments. Consider the software-write protect features if system security against accidental overwrites is critical. Verify that the operating temperature range of -40 °C to +125 °C aligns with the application's thermal constraints.

Memory IC Part Context

This part belongs to the BR25H080xxx-5AC series of serial EEPROMs designed specifically for automotive use. The series offers various package options including SOP-J8 and TSSOP-B8 to accommodate different board space requirements while maintaining consistent electrical characteristics and functional safety support across the family.

Memory IC Replacement Considerations

Check for exact pinout compatibility and identical memory organization (1024 x 8 bit) when substituting. Verify that any alternative component also holds AEC-Q100 qualification if automotive reliability is mandatory. Ensure the replacement supports the same SPI modes and voltage ranges.
