• Industrial automation systems utilizing real-time control logic
• Network infrastructure hardware demanding reliable volatile memory storage

Memory IC Procurement Notes

Verify the specific suffix 'BF' against official Renesas documentation to confirm the exact package type and temperature grade, as variations exist within the 70T651 family. Confirm RoHS compliance status, as some variants are non-compliant. Check for End-of-Life notices or Product Change Notifications regarding label changes or manufacturing site transfers before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a system requires simultaneous independent access to shared memory resources. Ensure the design accommodates the 2.4V to 2.6V power supply requirements and the physical dimensions of the 208-CABGA package. Verify that the 15ns access speed meets the timing constraints of the host processor or controller interface.

Memory IC Part Context

This part belongs to the 70T651 series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options to suit different performance and form-factor requirements. The 70T651S15BF specifically denotes the 15ns speed variant in the 208-lead CABGA package.

Memory IC Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully if considering generic equivalents, as dual-port SRAM interfaces can vary significantly between manufacturers.
