7164L20YGI8

Overview

The 7164L20YGI8 is a 64Kbit (8K x 8) asynchronous static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a parallel interface with a maximum access time of 20 ns and a write cycle time of 20 ns. The device operates within a supply voltage range of 4.5V to 5.5V and supports an industrial operating temperature range from -40°C to +85°C. It is housed in a 28-SOJ surface-mount package.

Feature Summary

• Asynchronous parallel SRAM architecture for high-speed data storage
• Industrial-grade temperature rating for reliable operation in harsh environments
• Single 5V power supply compatibility

Applications

• Industrial control systems requiring volatile memory
• Embedded applications needing fast random access
• Automotive electronics operating in extreme temperatures

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS3 compliance and moisture sensitivity level (MSL 3) requirements during handling. Check for specific suffix variations if alternative packaging or lead-free standards are required for the target assembly process.

Selection Notes

Select this part for designs requiring 64Kbit capacity with 20ns speed in a 28-pin SOJ package. Ensure the system voltage remains within 4.5V to 5.5V. Consider the industrial temperature range (-40°C to +85°C) for environmental suitability. Verify pinout compatibility if replacing legacy IDT components.

Part Context

This component belongs to the 7164L series of CMOS static RAMs. It is a successor to earlier IDT-branded versions, reflecting Renesas' acquisition of IDT's memory products. The 'YGI8' suffix typically denotes specific packaging and material compliance attributes within the Renesas portfolio.

Replacement Considerations

Direct substitutes include IDT7164L20YGI8. Other variants in the 7164L family with different speeds or packages may require schematic review.
