71V424L15YGI8

Overview

The IDT71V424L15YGI8 is a 4 Mbit (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 3.6 V and features a parallel interface with a maximum access time of 15 ns. The device is housed in a 36-BSOJ surface-mount package, specifically a 36-SOJ form factor with a width of 0.400 inches (10.16 mm). It supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous parallel SRAM architecture providing fast data access without external clock synchronization
• Industrial-grade thermal stability supporting reliable operation across extended temperature ranges
• CMOS technology enabling low power consumption during active and standby modes

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded computing systems
• Data storage for industrial control logic and automation hardware

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as original variants may differ from current manufacturing standards. Validate package dimensions against PCB footprint specifications before integration. Check for moisture sensitivity level handling procedures during assembly.

Selection Notes

Select this component when a 512K x 8 organization is required with 15 ns speed performance. Ensure the design accommodates the 36-SOJ surface-mount package constraints. Verify that the system voltage aligns with the 3 V to 3.6 V operational window. Consider alternative packages if higher density or different pin counts are needed.

Part Context

This part belongs to the IDT 71V424 family of high-performance asynchronous SRAMs. It shares architectural similarities with other members like the 71V424S10 series but differs in speed grade and packaging. The suffix YGI8 indicates specific material and packaging configurations distinct from standard tube versions.

Replacement Considerations

Direct substitutes include IDT71V424L15PHG and IDT71V424S10YG8. Verify pin compatibility and electrical parameters before substitution.
