• Zero Bus Turnaround (ZBT) architecture eliminates dead cycles between read and write operations
• Internally synchronized output buffer enable removes the need for external OE control
• Single R/W control pin simplifies interface logic requirements
• Positive clock-edge triggered registers support fully pipelined applications

Memory IC Applications

• High-performance system speed buffering
• Pipelined data processing applications
• Systems requiring simple depth expansion via multiple chip enables

Memory IC Procurement Notes

Verify part authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status, as some variants may not meet current environmental standards. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure thermal management aligns with specified operating temperatures.

Memory IC Selection Notes

Select this component for designs requiring high-speed synchronous memory with minimal turnaround latency. The 119-pin BGA package suits space-constrained surface-mount applications. Verify voltage compatibility with the 2.5V core and I/O supplies. Consider the single R/W control feature for simplified board layout compared to traditional SRAMs.

Memory IC Part Context

This device belongs to the 71T75802 series of ZBT synchronous SRAMs. It shares architectural similarities with other members like the 71T75802S133BGGI but differs in packaging and specific suffix designations. The series targets applications needing fast, reliable memory without complex bus turnaround timing constraints.

Memory IC Replacement Considerations

Direct substitutes include IDT71T75802S133BGGI and 71T75802S133BGG8. Verify pinout compatibility and electrical specifications before substitution. Note that some alternatives may have different moisture sensitivity levels or packaging variations.
