7164L20YGI

Overview

The IDT7164L20YGI is a high-speed static RAM organized as 8K by 8 bits, providing a total storage capacity of 64 kilobits. It utilizes asynchronous parallel interface technology and features a maximum access time of 20 nanoseconds. The device operates within a supply voltage range of 4.5 volts to 5.5 volts and supports a low-power standby mode when specific control signals are asserted. It is housed in a 28-lead Small Outline J-Lead (SOJ) surface-mount package designed for reliable electronic integration.

Feature Summary

• Asynchronous parallel memory interface for standard data transfer operations
• Low-power standby mode activated by chip select or output enable signals
• CMOS fabrication technology ensuring high reliability and performance

Applications

• General-purpose volatile data storage in embedded systems
• Buffer memory applications in digital signal processing circuits
• Cache memory implementation in microcontroller-based architectures

Procurement Notes

Verify the component status as discontinued with end-of-life notifications confirmed by the manufacturer. Confirm RoHS3 compliance and moisture sensitivity level requirements during handling. Ensure compatibility with existing 28-SOJ footprints and validate that the 20ns access speed meets system timing constraints before finalizing procurement decisions.

Selection Notes

Select this component when a 64Kb asynchronous SRAM with 20ns access speed is required in a surface-mount SOJ package. Consider the 4.5V to 5.5V operating voltage range and industrial temperature specifications. Evaluate alternative packages such as PDIP or CDIP if through-hole mounting is necessary for the specific application design.

Part Context

This part belongs to the IDT7164 family of 64Kbit CMOS static random-access memories. The 'L' suffix indicates low-power characteristics, while '20' denotes the 20-nanosecond access speed class. The 'YGI' suffix specifies the 28-lead SOJ surface-mount package configuration used in this specific variant.

Replacement Considerations

Publicly confirmed substitute part numbers include IDT7164L20TPG and IDT7164L20TP. These alternatives offer identical electrical specifications but utilize different package types such as 28-PDIP. Verify pinout compatibility and physical footprint differences before implementing any cross-package substitution.
