5962-3829406MZA

Memory IC Overview

The Renesas Electronics Corporation 5962-3829406MZA is a military-grade asynchronous static RAM organized as 8K x 8 bits. It operates from a single 5V supply and features TTL-compatible inputs and outputs with three-state capability. The device utilizes advanced CMOS high-performance technology for low power consumption and includes a reduced power standby mode. A specific low-power variant supports battery backup data retention at voltages as low as 2V. Access times are available in multiple grades, including -20, -25, -35, -45, -55, and -70ns maximums. It is housed in a 28-pin ceramic dual in-line package (CDIP) compliant with MIL-STD-883, Class B standards.

Memory IC Feature Summary

• Military-grade construction compliant with MIL-STD-883, Class B requirements
• Fully static asynchronous circuitry eliminating the need for clocks or refreshing
• Battery backup operation enabling data retention at supply levels as low as 2V
• TTL-compatible inputs and outputs simplifying system interface design

Memory IC Applications

• Military avionics systems requiring radiation-hardened or high-reliability memory
• Spacecraft onboard data storage and telemetry buffers
• Defense communication equipment needing non-volatile-like retention via battery backup
• Industrial control systems operating in extreme temperature environments

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to military compliance requirements. Confirm specific access time grade (-20 through -70ns) matches system timing constraints. Check for lead-free status if RoHS compliance is mandated, noting this specific part may not be lead-free. Ensure handling procedures align with MIL-STD-883 standards for ceramic packages. Validate that the 28-pin CDIP footprint matches the target PCB layout.

Memory IC Selection Notes

Select this component when strict MIL-STD-883 Class B reliability is required for 8K x 8 SRAM applications. Choose based on necessary access speed grades ranging from -20ns to -70ns. Consider the battery backup feature if power loss protection is critical without complex circuitry. Verify compatibility with 5V logic families due to TTL-compatible I/Os. Evaluate the 28-pin CDIP package suitability for through-hole mounting in ruggedized enclosures.

Memory IC Part Context

This part belongs to the 5962-38294 family of asynchronous SRAMs, widely used in defense and aerospace sectors. It serves as a direct replacement for legacy IDT 7164 devices under government contract specifications. The family offers various speed grades and package options within the same functional architecture. It represents a standard solution for high-reliability random access memory needs where commercial parts lack sufficient durability.

Memory IC Replacement Considerations

Direct equivalents include the IDT 7164 series under MIL-PRF-38535 specifications. Other compatible parts within the same organizational structure should match the 8K x 8 density and 5V operation. Verify pinout compatibility for the 28-pin CDIP package before substitution. Ensure any alternative meets the same MIL-STD-883 Class B qualification level.
