71V416S15YGI

Overview

The Renesas Electronics Corporation 71V416S15YGI is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) device. It operates within a supply voltage range of 3.0 V to 3.6 V and features a maximum access time of 15 ns. The component utilizes a parallel interface and is housed in a 44-pin Small Outline J-Lead (SOJ-44) surface-mount package. It supports Single Data Rate (SDR) storage technology and functions across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous operation with 15 ns access speed for rapid data retrieval
• Industrial-grade wide operating temperature range suitable for harsh environments
• CMOS technology ensuring low power consumption during active and standby modes

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded control systems
• Data storage in industrial automation controllers

Procurement Notes

Verify the current lifecycle status, as this part may be discontinued or subject to production changes. Confirm RoHS compliance details and moisture sensitivity level requirements before integration. Check for official product change notices regarding packaging or material substitutions. Ensure compatibility with existing board layouts due to the specific SOJ-44 footprint.

Selection Notes

Select this component when a 256K x 16 organization is required with 15 ns performance. The SOJ-44 package is distinct from TSOP options; verify pinout compatibility if replacing similar devices. Consider the extended -40°C to +85°C temperature range for applications exceeding commercial limits. Validate that the 3.3V nominal supply aligns with system power rails.

Part Context

This SRAM belongs to the 71V416S series, designed for high-reliability applications. The 'Y' suffix typically denotes the lead-free and RoHS-compliant variant, while 'GI' indicates the specific tape-and-reel or tube packaging configuration depending on the manufacturer's coding standards. It serves as a legacy component often found in established industrial designs.

Replacement Considerations

Officially documented substitutes include IDT71V416S15YG and 71V416S15PHG. Verify pin-to-pin compatibility and electrical specifications before substitution.
