7164S20YG

Overview

The Renesas Electronics Corporation 7164S20YG is a static random-access memory (SRAM) integrated circuit with a storage capacity of 64 kbit, organized as 8k x 8. It features an asynchronous parallel interface and a maximum access time of 20 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power supply current of 90 mA. It is housed in a surface-mount 28-SOJ package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Asynchronous parallel SRAM architecture for direct data bus interfacing
• BICMOS technology implementation for high-speed operation
• Single-density read/write functionality without page mode support

Applications

• Embedded systems requiring fast local data buffering
• Industrial control units needing volatile memory retention
• Consumer electronics utilizing standard 5V logic interfaces

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance and moisture sensitivity level handling requirements during assembly. Cross-reference datasheet revisions to ensure pinout and electrical characteristics match design specifications before integration into production workflows.

Selection Notes

Select this component when a 20 ns access speed and 64 kbit capacity are required in a 28-pin SOJ package. Ensure the application environment remains within the 0°C to +70°C operating temperature range. Verify that the system power supply strictly adheres to the 4.5 V to 5.5 V specification to maintain reliable asynchronous operation.

Part Context

This part belongs to the 7164S series of BICMOS static RAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family but is distinguished by its specific 20 ns access time and commercial temperature rating. The 28-SOJ package provides a compact footprint suitable for surface-mount applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the end-of-life status, alternative sourcing requires careful evaluation of functional equivalence and physical compatibility.
