71V416L12YGI

Overview

The IDT71V416L12YGI is a 4 Mbit (256K x 16) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It operates on a single 3.3 V supply voltage with a range of 3.0 V to 3.6 V. The device features a parallel interface and offers a maximum access time of 12 ns. It is housed in a 44-pin Small Outline J-Lead (SOJ) surface-mount package. The component supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Fully static asynchronous operation requiring no clock signals or periodic refresh cycles for data retention.
• Bidirectional inputs and outputs are LVTTL-compatible, ensuring direct interfacing with standard logic families.
• Center power and ground pinout configuration designed to minimize noise and improve signal integrity.

Applications

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

Procurement Notes

Verify the exact suffix against official Renesas documentation, as variations such as YGI may indicate specific packaging or environmental compliance differences. Confirm current availability status, as this component series has been subject to discontinuation notices. Ensure compatibility with existing board layouts regarding the 44-SOJ footprint and center power/ground pin arrangement before procurement.

Selection Notes

Select this component when a 12 ns access speed is required for 256K x 16 word organization. It is suitable for designs needing LVTTL-compatible I/O levels without external level shifting. Consider the 44-SOJ package constraints and the -40°C to +85°C temperature rating for industrial environments. Verify if lead-free or RoHS-compliant variants are available if regulatory compliance is mandatory.

Part Context

This part belongs to the 71V416 family of high-speed CMOS SRAMs. The family includes variants with different access speeds and package types, such as TSOP and SOJ. The 'L' designation typically denotes lower power consumption characteristics compared to other series members. Renesas acquired the IDT product line, so legacy IDT branding often appears alongside Renesas part numbers.

Replacement Considerations

Check for direct cross-references within the 71V416L12 series. Verify pin-to-pin compatibility with alternative suppliers offering 256K x 16 SRAMs in 44-SOJ packages. Ensure replacement parts match the 12 ns access time and 3.3 V operating voltage specifications.
