71V424L15YGI

Overview

The IDT71V424L15YGI is a 4-Mbit (512K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. 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 device is housed in a 36-lead BSOJ package designed for surface-mount installation. It supports an industrial operating temperature range from -40°C to +85°C. This component is classified as a single-density SRAM suitable for high-speed data buffering applications.

Feature Summary

• Asynchronous parallel operation for flexible system integration
• High-speed data access with 15 ns cycle time
• Industrial-grade thermal stability across wide temperature ranges

Applications

• Data buffering in telecommunications equipment
• Cache memory in embedded control systems
• High-speed data acquisition modules

Procurement Notes

Verify the specific suffix YGI against current manufacturer documentation, as legacy IDT part numbers often have complex revision histories. Confirm RoHS compliance status, as older batches may not meet current environmental standards. Check for official discontinuation notices or product change notifications that may affect long-term availability or pin compatibility. Ensure the 36-SOJ package dimensions match the target PCB footprint exactly.

Selection Notes

Select this component when a 512K x 8 organization is required with 15 ns speed performance. Compare against the 71V424L10 series if faster access times are needed, noting potential pinout differences. Verify power consumption requirements against the typical specifications for 3.3V CMOS technology. Ensure the design accommodates the specific lead form factor of the BSOJ package for proper reflow soldering profiles.

Part Context

This part belongs to the IDT 71V424 family of asynchronous SRAMs, originally developed by Integrated Device Technology before its acquisition by Renesas. The L-series typically denotes lower power variants compared to standard S-series devices. These components were widely used in legacy industrial and communication hardware requiring fast, volatile memory storage without complex refresh cycles.

Replacement Considerations

• 71V424L10YGI
• 71V424L15PHG

FAQ

Is the IDT71V424L15YGI RoHS compliant?

RoHS compliance varies by manufacturing date and specific production batch. Users must verify the compliance status directly on the datasheet or through official procurement channels, as earlier versions may not meet current regulations.

What is the difference between the YGI and PHG suffixes?

Suffixes typically indicate variations in packaging type, lead finish, or environmental compliance. The YGI suffix corresponds to the 36-SOJ package, while PHG often indicates a TSOP II package. Pinouts and physical dimensions differ between these packages.
