71V424S15YGI8

Overview

The 71V424S15YGI8 is a 4 Mbit (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics. It features a parallel interface with a maximum access time of 15 ns and operates within a supply voltage range of 3.0 V to 3.6 V. The component supports single data rate (SDR) operation and has a maximum power supply current of 170 mA. It is housed in a 36-pin SOJ package designed for surface-mount technology. The device is rated for an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous parallel SRAM architecture providing 4 Mbit storage capacity
• High-speed 15 ns access time for rapid data retrieval
• Industrial-grade temperature rating suitable for demanding environments
• CMOS technology ensuring low power consumption during operation

Applications

• Embedded systems requiring fast local data storage
• Industrial control units needing reliable memory solutions
• Telecommunications equipment buffer applications
• Automotive electronics modules operating in harsh conditions

Procurement Notes

Verify the specific package variant, as the 71V424S15 series includes different pin counts such as 36-pin SOJ. Confirm that the 512K x 8 organization matches your design requirements, as some datasheets may list alternative organizations like 256K x 16 for similar part numbers. Ensure the 3.0 V to 3.6 V supply voltage aligns with your system's power rails. Check for RoHS compliance status if required by your manufacturing standards. Validate the lead times and availability directly with authorized distributors due to potential supply chain fluctuations.

Selection Notes

Select this component when a 4 Mbit capacity with 15 ns speed is required in a compact surface-mount form factor. The 36-pin SOJ package is ideal for space-constrained designs where through-hole mounting is not feasible. Consider the -40°C to +85°C operating range for industrial or automotive applications. Compare against other members of the 71V424S15 family to ensure the correct voltage and organizational configuration meets your specific circuit needs.

Part Context

This part belongs to the Renesas 71V424S15 series of high-speed asynchronous SRAMs. The series offers various configurations and packages to suit different design constraints. The 71V424S15YGI8 specifically utilizes the SOJ-36 package, distinguishing it from TSOP or PLCC variants within the same electrical family. This series is known for its compatibility with standard microprocessor interfaces and robust performance in embedded memory applications.

Replacement Considerations

Direct substitutes include other 71V424S15 series parts with identical electrical specifications but different packages, such as the 71V424S15PHGI8 if a TSOP package is acceptable. Verify pinout compatibility before swapping packages. Cross-reference with IDT equivalents if sourcing from alternate manufacturers, ensuring the 512K x 8 organization and 15 ns speed are maintained.
