Memory IC Procurement Notes

This component has reached end-of-life status and is officially discontinued by Renesas Electronics Corporation. Availability is strictly limited to existing stock held by distributors or secondary market suppliers. Verify authenticity and physical condition carefully, as no new manufacturing occurs. Confirm specific suffix compatibility if substituting within the legacy family.

Memory IC Selection Notes

Select this part only when a 200 MHz synchronous dual-port SRAM with 36-bit width is required. Ensure the design accommodates the 2.4V to 2.6V supply voltage range and the 256-pin CABGA footprint. Consider that the device is obsolete; evaluate long-term supply chain stability and potential migration paths to newer memory technologies before finalizing the design.

Memory IC Part Context

The 70T3319 series belongs to Renesas' portfolio of high-performance synchronous dual-port RAMs. These devices are engineered for applications demanding concurrent read/write operations without arbitration delays.
