7164L20YG

Overview

The 7164L20YG is a 64Kb (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 operates within a supply voltage range of 4.5V to 5.5V. The device is housed in a 28-SOJ surface-mount package and supports an industrial operating temperature range from -40°C to +85°C.

Feature Summary

• Asynchronous parallel SRAM architecture for high-speed data storage
• Industrial-grade wide temperature operation capability
• Standard 5V logic compatibility

Applications

• Industrial control systems requiring reliable volatile memory
• Embedded applications with strict thermal constraints
• Legacy hardware maintenance and replacement

Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Procurement must rely exclusively on authorized distributors or certified secondary market suppliers. Verify authenticity through official traceability documentation, as EOL status increases exposure to counterfeit risks. Confirm RoHS3 compliance and specific suffix variations before acquisition.

Selection Notes

Select this part only when legacy system compatibility with 20ns access speed and 5V logic levels is mandatory. Ensure the design accommodates the 28-SOJ footprint and industrial temperature specifications. Evaluate alternative modern SRAMs if form factor or power constraints allow, considering the discontinued status limits long-term supply availability.

Part Context

Part of the IDT 7164L series, this device represents a standard 64Kb asynchronous SRAM solution. It was widely used in embedded systems prior to the industry shift toward higher density and lower voltage technologies. The 'YGI' suffix denotes the specific SOJ package and industrial temperature grade configuration.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific variant. Designers should consult Renesas for current portfolio equivalents that match the 28-SOJ package and 20ns performance metrics.
