71V424S10YGI

Overview

The 71V424S10YGI is a 4 Mbit (512K x 8) asynchronous static random-access memory manufactured by Renesas Electronics. 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 10 ns. The device supports single data rate operation and is housed in a 36-SOJ surface-mount package. It is rated for an industrial temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous parallel SRAM architecture providing non-clock-dependent data access
• CMOS technology designed for low power consumption during standby and active modes
• Industrial-grade thermal stability supporting reliable operation across wide temperature variations

Applications

• Embedded systems requiring fast local data storage
• Industrial control equipment needing volatile memory buffers
• Telecommunications infrastructure components

Procurement Notes

This component has reached end-of-life status and is no longer manufactured by Renesas Electronics. Verification of authenticity is critical when sourcing remaining stock, as the part may be available only through third-party distributors or surplus channels. Buyers must confirm the specific revision and packaging condition prior to acquisition due to discontinuation.

Selection Notes

Engineers should evaluate alternative components from the same family or compatible manufacturers before finalizing designs. Considerations include verifying pin compatibility, ensuring equivalent access speeds, and confirming that replacement parts support the required voltage and temperature specifications. Legacy design maintenance often requires identifying direct substitutes with matching form factors.

Part Context

The 71V424S10YGI belongs to the IDT 71V424 series of high-performance SRAMs. This series was widely used in applications demanding rapid data retrieval without complex clock synchronization. The suffix YGI denotes the specific package type and temperature rating, distinguishing it from other variants in the broader product line.

Replacement Considerations

Verified substitute part numbers include 71V424S10PHG8 and AS7C34096A-10JCN. These alternatives offer similar capacity and speed characteristics but may differ in package dimensions or manufacturer-specific electrical tolerances.
