7164L20TPG

Overview

The IDT7164L20TPG is a static random-access memory integrated circuit manufactured by Renesas Electronics Corporation. It features an asynchronous parallel interface with a storage capacity of 64Kb, organized as 8K words by 8 bits. The device operates within a supply voltage range of 4.5V to 5.5V and supports access times of 20ns. It is housed in a 28-pin plastic dual in-line package (PDIP) designed for through-hole mounting. The component functions within a commercial operating temperature range of 0°C to 70°C.

Feature Summary

• Asynchronous parallel SRAM architecture requiring no clock signals or refresh cycles
• Single 5V power supply operation compatible with standard logic levels
• Through-hole 28-pin PDIP packaging suitable for prototyping and legacy systems

Applications

• Embedded system data buffering
• Industrial control unit temporary storage
• Consumer appliance logic circuits

Procurement Notes

Verify the specific suffix 'TPG' against official Renesas documentation to confirm the exact package variant and RoHS compliance status. Confirm end-of-life status via recent Product Change Notices, as availability may be restricted. Ensure the procurement channel provides traceable origin documents to validate authenticity for critical applications.

Selection Notes

Select this component when a 64Kb asynchronous memory solution with 20ns speed is required for through-hole assembly. Compare against the 7164L20YGI if surface-mount technology is preferred instead. Verify that the 4.5V to 5.5V voltage range aligns with the target system's power rails and that the commercial temperature range meets environmental requirements.

Part Context

This part belongs to the 7164L series of high-speed CMOS static RAMs originally developed by Integrated Device Technology (IDT) and now managed by Renesas Electronics. The series provides non-volatile-like performance without the complexity of flash programming, serving as a bridge between fast processor speeds and slower external storage devices in embedded architectures.

Replacement Considerations

The 7164L20TP is a verified substitute offering identical electrical specifications and pinout compatibility in the same 28-PDIP package.
