7164L20TDB

Memory IC Overview

The Renesas Electronics Corporation 7164L20TDB is a 64Kb (8K x 8) asynchronous static random-access memory (SRAM) IC. It features a parallel interface with a 20 ns access time and write cycle time. The device operates on a single 5V power supply ranging from 4.5V to 5.5V. It is housed in a 28-pin Ceramic Dual In-Line Package (CDIP-28). The component supports an industrial operating temperature range of -55°C to +125°C.

Memory IC Feature Summary

Asynchronous SRAM technology for high-speed data storage
Parallel interface supporting standard bus architectures
Industrial-grade wide temperature operation capability
Single 5V power supply requirement

Memory IC Applications

Industrial control systems requiring wide temperature tolerance
Embedded memory solutions for harsh environment applications
Data buffering in high-reliability electronic equipment

Memory IC Procurement Notes

Verify the specific suffix 'TDB' against official Renesas documentation to confirm the CDIP-28 ceramic package and -55°C to +125°C temperature range, as suffixes define physical and environmental specifications. Confirm current lifecycle status, as this part may be obsolete or subject to production changes. Ensure compatibility with existing system voltage levels and thermal management requirements before procurement.

Memory IC Selection Notes

Select this component when a 64Kb capacity with 20 ns speed is required in a ruggedized ceramic package. The wide temperature range makes it suitable for environments exceeding standard commercial limits. Compare against other 7164L variants to ensure the specific package type and temperature grade match the design constraints. Verify pinout compatibility if replacing older IDT versions.

Memory IC Part Context

The 7164L series represents a family of 64Kb asynchronous SRAMs manufactured by Renesas Electronics. This specific model utilizes BICMOS technology to balance performance and power consumption. The 7164L20 designation indicates the 20 ns speed grade within the product line, distinguishing it from slower variants like the 70 ns or 85 ns versions.
