IDT7164L20TP

Memory IC Overview

The IDT7164L20TP is a 64Kb (8K x 8) asynchronous static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It features a parallel interface with a maximum access time of 20 ns and a write cycle time of 20 ns. The device operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of 0°C to 70°C. It is housed in a 28-pin dual in-line package (PDIP) designed for through-hole mounting.

Memory IC Feature Summary

• Asynchronous parallel SRAM architecture providing non-clock-dependent data access.

Memory IC Applications

• General-purpose volatile memory storage in industrial control systems.

Memory IC Procurement Notes

Verify the specific suffix 'TP' against official Renesas documentation to confirm the exact package variant and lead-free status, as suffixes define physical form factors. Confirm current lifecycle status, as this component may be subject to end-of-life notices or production transfers. Ensure compatibility with existing PCB footprints for 28-PDIP through-hole assembly before procurement.

Memory IC Selection Notes

Select this component when a 64Kb capacity with 20 ns speed is required for through-hole applications. Compare against other 7164L variants if surface-mount options like SOJ are acceptable for space-constrained designs. Verify that the 4.5V to 5.5V supply requirement aligns with the system's power rails, as lower voltage 3.3V SRAMs exist in different product families.

Memory IC Part Context

This part belongs to the IDT 7164L series of high-speed CMOS static RAMs. The series offers various access speeds and packaging options to suit different design constraints. Renesas acquired the IDT memory portfolio, maintaining these legacy parts for continued support in established hardware platforms requiring reliable, fast asynchronous memory solutions.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the same 7164L family, such as different speed grades or package types (e.g., 7164L20YGI for SOJ). Verify if newer generations from Renesas offer equivalent performance with improved environmental compliance or availability.
