Procurement Notes

This component has reached End-of-Life status and is no longer manufactured. Verification of availability should focus on existing stock from authorized distributors or approved replacement part numbers. Ensure that any substitute components meet the original electrical specifications, pinout compatibility, and thermal requirements before integration into the design.

Selection Notes

Select this component when a 9Mb capacity with 18-bit word width is required for synchronous parallel applications. The 150 MHz speed class and 3.8 ns access time suit high-throughput data processing tasks. Verify that the system power supply strictly adheres to the 3.135V to 3.465V range to ensure reliable operation within the specified industrial temperature limits.

Part Context

The 71V65803 series belongs to Renesas' portfolio of high-performance synchronous SRAMs designed for demanding embedded applications. This specific model utilizes advanced CMOS technology to deliver low power consumption while maintaining high bandwidth. The TQFP package offers a compact footprint suitable for space-constrained printed circuit board layouts in professional electronic devices.

Replacement Considerations

Verify cross-references with other variants in the 71V65803 family, such as different speed grades or package types, ensuring they match the required 150 MHz performance and 100-pin form factor for direct substitution.
