71V416S12YGI

Overview

The 71V416S12YGI is a 3.3V CMOS static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features an organized capacity of 256K x 16 bits, providing a total storage of 4 Mbit. The device utilizes asynchronous parallel interface technology with a specified access time of 12 ns. It operates within a supply voltage range of 3 V to 3.6 V and supports surface-mount installation in a 44-pin SOJ package. The component is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Fully static asynchronous circuitry requiring no clock signals or refresh cycles for operation.
• Bidirectional inputs and outputs are LVTTL-compatible for direct interfacing with logic systems.
• Single 3.3V power supply operation simplifies power distribution design.

Applications

• Buffering data in high-speed digital signal processing systems
• Cache memory implementation in embedded controllers
• Temporary data storage in industrial automation equipment

Procurement Notes

Verify current availability status as the component may be discontinued or subject to limited supply constraints. Confirm moisture sensitivity level handling requirements during storage and assembly. Ensure compatibility with existing PCB footprints and verify that the 44-SOJ package dimensions match design specifications. Check for RoHS compliance documentation if required for specific regulatory standards.

Selection Notes

Select this part when a 12 ns access speed is required for 256K x 16 bit SRAM applications. Consider the 44-SOJ package constraint for board layout. Evaluate thermal performance within the -40°C to +85°C operating range. Compare against faster variants like the 10 ns version if timing margins are tight, or slower versions if cost reduction is prioritized over speed.

Part Context

This component belongs to the 71V416S series of 3.3V CMOS SRAMs. It shares architectural similarities with other members of the family, differing primarily in access speed and packaging options. The series is designed for general-purpose memory applications requiring reliable, non-volatile-free storage solutions in compact form factors.

Replacement Considerations

The IDT71V416S12YGI is listed as an alias for this part number. Verify pinout compatibility before substitution. Other speeds in the same package, such as 71V416S10YG, offer faster access but may require timing adjustment.
