5962-3829413MXA

Memory IC Overview

The Renesas Electronics Corporation 5962-3829413MXA is a military-grade, fully static asynchronous SRAM organized as 8K x 8 bits. It operates from a single 5V supply with TTL-compatible inputs and outputs. The device features high-speed access times of 70ns maximum and includes a reduced power standby mode. A low-power variant supports battery backup data retention at voltages as low as 2V. It is housed in a 28-pin ceramic dual in-line package (CDIP) and complies with MIL-STD-883, Class B requirements.

Memory IC Feature Summary

• Military-grade construction compliant with MIL-STD-883, Class B standards for harsh environment reliability.
• Fully static asynchronous architecture requiring no clock signals or periodic refreshing for operation.
• Integrated reduced power standby mode to minimize energy consumption during idle periods.
• Battery backup capability allowing data retention at supply levels as low as 2V.

Memory IC Applications

• Military avionics systems requiring radiation-hardened or high-reliability memory storage.
• Spacecraft guidance and control subsystems utilizing MIL-PRF-38535 qualified components.
• Industrial automation controllers operating in extreme temperature environments.
• Defense communication equipment needing non-volatile-like data preservation via battery backup.

Memory IC Procurement Notes

Verify the specific suffix MXA against official Renesas documentation to confirm package dimensions and lead finish specifications. Confirm that the MIL-STD-883 Class B compliance meets your project's environmental qualification requirements. Check for discontinuation notices as this component may be subject to end-of-life status. Ensure compatibility with existing 5V logic interfaces before integration into new designs.

Memory IC Selection Notes

Select this component when a fully static, asynchronous memory solution is required for military or industrial applications. It is suitable for designs needing TTL compatibility without level shifting. Consider the battery backup feature if data preservation during power loss is critical. Evaluate the 28-pin CDIP package constraints against available board space and mounting methods.

Memory IC Part Context

This part belongs to the 5962-38294 family of 8K x 8 asynchronous SRAMs. The family offers various speed grades and packaging options tailored for high-reliability markets. These devices are designed to replace older bipolar SRAM technologies with more efficient CMOS implementations while maintaining pin-out compatibility.

Memory IC Replacement Considerations

Direct replacements must match the 8K x 8 organization, 5V operation, and 28-pin CDIP package. Verify that any substitute also holds MIL-STD-883 Class B certification. Cross-reference speed grades to ensure timing requirements are met. Note that newer CMOS generations may require different voltage tolerances.
