7164L35TPGI

Overview

The Renesas Electronics Corporation 7164L35TPGI is an asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features a parallel interface with a maximum access time of 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports a working temperature range from -40°C to +85°C. The component is housed in a 28-pin plastic dual in-line package (PDIP).

Feature Summary

• Asynchronous SRAM technology for volatile data storage.
• Parallel interface supporting standard digital logic connections.
• Industrial-grade operational temperature range capability.

Applications

• Embedded systems requiring fast local data buffering.
• Industrial control equipment operating in variable thermal environments.
• Telecommunications hardware utilizing parallel memory interfaces.

Procurement Notes

Verify the specific suffix TPGI confirms the 28-PDIP package and industrial temperature rating. Confirm the manufacturer designation as Renesas Electronics Corporation or its predecessor IDT. Check for end-of-life notices, as this component may be discontinued. Ensure compatibility with existing 5V logic levels and board space constraints for through-hole mounting.

Selection Notes

Select this component when a 64Kbit asynchronous SRAM with a 35ns access speed is required. It is suitable for designs needing through-hole packaging for mechanical stability. Consider alternatives if lower power consumption or smaller surface-mount packages are necessary. Verify that the system voltage aligns with the 4.5V to 5.5V operating range.
