7164L45TDB

Memory IC Overview

The 7164L45TDB is a 64 Kbit (8K x 8) asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It utilizes parallel interface technology with a maximum access time of 45 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports single data rate (SDR) storage. It is housed in a 28-lead Ceramic Dual In-Line Package (CDIP). The component is classified as an end-of-life product scheduled for discontinuation.

Memory IC Feature Summary

• Asynchronous SRAM architecture providing non-synchronized data access via parallel interface
• High-speed 45 ns access time for rapid read operations
• Robust ceramic dual in-line package construction suitable for demanding environments

Memory IC Applications

• Industrial automation control systems
• Embedded computer memory modules
• Test and measurement equipment data storage

Memory IC Procurement Notes

Verify current availability status as the component is designated as End of Life. Confirm compliance with export control regulations, particularly regarding United States export restrictions. Ensure compatibility with existing system voltage requirements of 4.5 V to 5.5 V. Check for any additional documentation required for international shipping or customs clearance.

Memory IC Selection Notes

Select this component only if legacy support for 28-lead CDIP packaging is mandatory. Verify that the 45 ns access speed meets system timing constraints. Consider the end-of-life status when planning long-term production lifecycles. Ensure the design accommodates the specific power supply voltage tolerances defined for the 7024L series family.

Memory IC Part Context

This part belongs to the Renesas 7164L45 series of high-speed SRAMs. It shares architectural similarities with other members like the 7024L45J but differs in memory organization and package type. The series is designed for applications requiring reliable, fast asynchronous memory in industrial and embedded contexts.

Memory IC Replacement Considerations

No direct public substitute part numbers are confirmed for this specific variant. Evaluate cross-reference options such as IDT7164S45L32B8 only after verifying pinout and electrical parameter compatibility.
