Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as packaging variations exist within this product family. Confirm current lifecycle status, as availability may be limited due to end-of-life notices. Ensure compatibility with 3.3V logic levels and 100-TQFP footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 256K x 18 organization is required for synchronous memory applications. Consider the 133 MHz speed grade and 4.2 ns access time for timing-critical designs. Verify that the 100-TQFP package dimensions fit the target PCB layout constraints and that the operating temperature range meets system specifications.

Part Context

This part belongs to the Renesas 71V3578 series of synchronous SRAM devices. These components are designed for applications demanding high bandwidth and low latency. The series typically includes variants with different access speeds and package options, all sharing the same core memory architecture and pinout compatibility within specific speed grades.

Replacement Considerations

IS61LPS25618A-200TQLI is listed as a potential substitute. Verify electrical parameter compatibility and pin-to-pin equivalence before implementation.
