Memory IC Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Distribution availability is restricted or non-existent in many regions. Verify specific lot dates and authenticity carefully when sourcing from secondary markets due to discontinuation status.

Memory IC Selection Notes

Select this part only if legacy compatibility with the 7134SA series is required. Ensure the design accommodates the CDIP-SB-48 through-hole package constraints. Consider the 70 ns access speed against modern alternatives if performance upgrades are feasible for the target application.

Memory IC Part Context

The 7134SA70CB belongs to the Renesas 7134SA family of dual-port SRAMs. It shares functional similarities with other variants like the 7134SA70J but differs in packaging and thermal specifications. This series was widely used in applications demanding independent read/write ports without external arbitration logic.

Memory IC Replacement Considerations

Public confirmed substitute part numbers are not available for this discontinued component. Evaluate cross-reference options such as IDT7134SA70CB equivalents or newer dual-port SRAM families from Renesas or other manufacturers based on pinout and electrical compatibility.
