7164L20DB

Overview

The Renesas Electronics Corporation 7164L20DB is a 64Kbit asynchronous static random-access memory (SRAM) integrated circuit. It features a parallel interface with an 8K x 8 memory organization and a 20ns access time. The device operates on a single 5V supply within the 4.5V to 5.5V range. It includes a reduced power standby mode for low-power applications. The component is designed for through-hole mounting in a standard package configuration.

Feature Summary

• Asynchronous parallel SRAM architecture
• Single 5V CMOS operation
• Reduced power standby mode

Applications

• General-purpose volatile data storage
• Industrial control systems
• Embedded system memory buffers

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and temperature rating, as variations exist within the 7164L family. Confirm end-of-life status and last-time-buy dates via authorized distributors, as this component may be discontinued or subject to product change notices. Ensure compatibility with existing board layouts regarding pinout and mounting style before procurement.

Selection Notes

Select this component when a through-hole asynchronous SRAM with 64Kbit capacity is required. Compare access times and voltage ranges against other 7164L variants to ensure fit for the specific application timing and power constraints. Verify that the parallel interface matches the host controller's memory bus requirements.

Part Context

The 7164L series consists of high-speed CMOS static RAMs manufactured by Renesas Electronics. These devices are organized as 8K x 8 bits and offer fast access times suitable for various computing and industrial applications. The series supports both surface mount and through-hole packages depending on the specific suffix.

Replacement Considerations

Check for direct pin-compatible replacements within the 7164L family, such as different speed grades or package options. Verify if newer generations from Renesas or other manufacturers offer equivalent specifications with improved availability.
