7164S20YG

Memory IC Overview

The IDT 7164S20YG is a CMOS Static RAM with a capacity of 64K bits, organized as 8K words by 8 bits. It features an asynchronous parallel interface with a maximum access time of 20 nanoseconds. The device operates on a single 5V power supply within the range of 4.5V to 5.5V. It is housed in a 28-pin Small Outline J-Lead (SOJ) package designed for surface mount installation. The component supports a commercial operating temperature range from 0°C to 70°C.

Memory IC Feature Summary

• Asynchronous parallel memory architecture for standard data storage
• CMOS technology ensuring low power consumption and high speed
• Single voltage supply operation compatible with standard logic levels

Memory IC Applications

• General-purpose volatile memory storage in embedded systems

Memory IC Procurement Notes

Verify the specific suffix against official Renesas or IDT documentation to confirm pinout compatibility and electrical characteristics. Confirm RoHS compliance status as manufacturing sources may vary. Check for obsolescence notices since this component family has undergone production transfers. Ensure the SOJ package width matches your PCB footprint requirements before ordering.

Memory IC Selection Notes

Select this part when a compact surface-mount SRAM solution is required for 64K-bit capacity needs. The 20ns access time suits moderate-speed asynchronous applications. Consider the 28-SOJ package constraints regarding board space and thermal dissipation. Verify that the 5V logic levels align with the system's I/O voltage standards.

Memory IC Part Context

This component belongs to the IDT 7164S series of static random-access memories. The series provides reliable non-volatile-like performance for volatile storage in digital circuits. IDT was acquired by Renesas Electronics, which continues to support these legacy parts. The 7164S designation indicates the 64K-bit density class within the product line.

Memory IC Replacement Considerations

Cross-reference with IDT7164S20YGI or Renesas equivalents for updated packaging or compliance versions. Verify functional compatibility with other 8Kx8 20ns SOJ SRAMs if sourcing from alternative manufacturers.
