71V416S15YG

Overview

The Renesas Electronics Corporation 71V416S15YG is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) integrated circuit. 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 44-lead Small Outline J-Lead (SOJ) surface-mount package, specifically identified as 44-BSOJ with a width of 0.400 inches (10.16 mm). It supports single data rate (SDR) operations and functions within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous parallel SRAM architecture providing fast data access for system memory applications
• CMOS technology ensuring low power consumption during operation
• Surface-mount SOJ packaging designed for automated assembly processes

Applications

• Industrial control systems requiring reliable volatile memory storage
• Consumer electronics utilizing 3.3V logic interfaces
• Embedded computing modules needing high-speed data buffering

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3) handling requirements. Check for manufacturer-recommended replacements such as the 71V416S15PHG variant if current stock is unavailable. Ensure design-in compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component for designs requiring 4 Mbit capacity with 15 ns speed in a 44-SOJ package. Verify that the operating environment stays within the commercial temperature range of 0°C to 70°C. Consider the industrial-grade 71V416S15YGI if extended temperature support (-40°C to 85°C) is required instead.

Part Context

This part belongs to the IDT/Renesas 71V416S family of high-performance asynchronous SRAMs. These devices are widely used in legacy and modern embedded systems where fast, random-access memory is critical. The 71V416S15YG represents the commercial temperature grade version of this series.

Replacement Considerations

The 71V416S15PHG is listed as a manufacturer-recommended replacement. Note that the PHG suffix typically indicates a TSOP-44 package rather than the original SOJ form factor, requiring footprint verification.
