7164L45TPGI

Overview

The Renesas Electronics Corporation 7164L45TPGI is a 64Kbit (8K x 8) asynchronous static random-access memory (SRAM) IC. It features a parallel interface and operates within a supply voltage range of 4.5V to 5.5V. The component has an access time of 45ns and supports through-hole mounting in a 28-PDIP package with a width of 0.300 inches (7.62mm). It functions as volatile memory and is rated for an operating temperature range of 0°C to 70°C.

Feature Summary

Asynchronous parallel memory architecture for standard data storage applications
Single power supply operation compatible with 5V logic systems
Through-hole packaging suitable for general-purpose circuit board integration

Applications

General-purpose volatile data storage in industrial control systems
Buffer memory in embedded microcontroller designs
Data holding in legacy computer peripheral interfaces

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations may exist. Confirm that the 28-DIP package dimensions match your PCB footprint requirements precisely. Ensure that the 4.5V to 5.5V supply voltage range aligns with your system's power rails. Check for any specific handling instructions related to its status as a discontinued or end-of-life product if applicable in your region.

Selection Notes

Select this component when a 64Kbit capacity with 45ns access speed is required for 5V asynchronous applications. The 28-pin DIP package is appropriate for prototyping or through-hole manufacturing processes. Consider alternative packages if surface-mount technology is preferred, or faster access times if system latency is critical. Verify compatibility with existing 5V logic levels before integration.

Part Context

This part belongs to the 7164L series of asynchronous SRAMs from Renesas Electronics. It provides non-volatile-like retention during power but loses data upon power loss. The 7164L series is designed for cost-effective memory expansion in 8-bit and 16-bit systems. It serves as a foundational memory component for older or specialized industrial equipment requiring reliable parallel data access.
