71V416S15PHG

Overview

The IDT71V416S15PHG is a 4-Mbit (256K x 16) asynchronous static random-access memory manufactured by Renesas Electronics. It features a parallel interface and operates within a supply voltage range of 3.0 V to 3.6 V. The component provides an access time of 15 ns and supports surface-mount installation in a 44-pin TSOP package. It is designed for industrial temperature ranges, functioning reliably between -40°C and +85°C.

Feature Summary

• Asynchronous parallel SRAM architecture with 256K x 16 organization
• Industrial-grade operational capability across extended temperature ranges
• CMOS technology optimized for low power consumption

Applications

• Data buffering in high-speed digital systems
• Cache memory implementation in embedded controllers
• Storage applications in telecommunications equipment

Procurement Notes

Verify the specific suffix PHG against official datasheets to confirm the TSOP-44 package type and lead-free status. Confirm RoHS compliance requirements as manufacturing sites may vary. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability and sourcing strategies.

Selection Notes

Select this component when a 15 ns access speed is required for 16-bit wide data paths. Ensure the design accommodates the 3.0 V to 3.6 V supply voltage constraints. Verify that the PCB layout supports the 44-TSOP footprint and that thermal management meets the -40°C to +85°C operating specifications.

Part Context

This part belongs to the 71V416 family of high-speed SRAMs from Renesas. The 'S' designation typically indicates a SOJ/TSOP package variant, while '15' denotes the 15 ns speed grade. This series is engineered for applications requiring fast random access without the complexity of synchronous clocking interfaces.

Replacement Considerations

Officially recommended substitutes include the 71V416S15PHGI and 71V416S15YGI. These variants share identical electrical characteristics but differ in packaging or environmental compliance details.
