7164S20TPGI

Overview

The Renesas Electronics Corporation 7164S20TPGI is a 64Kbit (8K x 8) asynchronous static random-access memory (SRAM) integrated circuit. It utilizes a parallel interface with a maximum access time of 20 nanoseconds and a write cycle time of 20 nanoseconds. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of -40°C to +85°C. It is housed in a 28-pin dual in-line package (DIP) designed for through-hole mounting.

Feature Summary

• Asynchronous parallel SRAM architecture providing 64Kbit storage capacity organized as 8K words by 8 bits.
• High-speed data access with a 20ns access time and write cycle duration for efficient system integration.
• Robust industrial-grade thermal performance supporting operation from -40°C to +85°C.
• Standard 28-pin DIP physical form factor facilitating through-hole PCB installation.

Applications

• Industrial control systems requiring reliable volatile memory storage
• Embedded applications utilizing standard parallel bus interfaces
• Legacy hardware maintenance and replacement scenarios

Procurement Notes

Verify component authenticity due to obsolete status. Confirm package integrity and pin alignment against the 28-DIP specification. Ensure supply voltage compatibility within the 4.5V to 5.5V range before integration. Check for moisture sensitivity handling requirements during storage and assembly processes.

Selection Notes

Select this component when a 20ns asynchronous parallel SRAM is required for through-hole designs. Consider the industrial temperature range (-40°C to +85°C) for harsh environments. Evaluate the 28-DIP footprint compatibility with existing PCB layouts. Verify that the 64Kbit capacity meets specific memory organization needs.
