5962-8976408MXA

Overview

The Renesas Electronics Corporation 5962-8976408MXA is a military-grade dual-port static random-access memory (SRAM) component. It features a 4K x 8 organization with true dual-ported memory cells allowing simultaneous access to the same location. The device operates asynchronously from either port and supports battery backup operation with data retention at 2V. It utilizes a TTL-compatible single 5V power supply and is housed in a 48-pin ceramic flatpack package.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations without hardware arbitration.
• Fully asynchronous operation from both ports, eliminating the need for clock synchronization or refresh cycles.
• Battery backup capability ensuring data retention at low voltage levels of 2V.
• Military compliance meeting MIL-PRF-38535 QML requirements for high-reliability applications.

Applications

• Systems requiring on-chip hardware port arbitration avoidance
• Applications intolerant of wait states during memory access
• External arbitration systems handling simultaneous Dual-Port RAM contention

Procurement Notes

Verify component authenticity through authorized channels due to military grade status. Confirm package integrity as the unit uses a ceramic flatpack construction. Check for RoHS compliance documentation as indicated by manufacturer specifications. Validate part number suffixes against official datasheets to ensure correct pinout and electrical characteristics. Review discontinuation notices if sourcing from secondary markets.

Selection Notes

Select this component when system design requires independent concurrent access to shared memory without external arbitration logic. Suitable for environments where asynchronous operation simplifies timing constraints. Consider the ceramic flatpack package for thermal and mechanical robustness in harsh conditions. Ensure compatibility with 5V TTL logic levels and verify battery backup circuit integration for data preservation.

Part Context

This part belongs to the 5962-89764 series of high-speed dual-port SRAMs manufactured by Renesas Electronics. It is designed for military and aerospace applications requiring high reliability and radiation hardness considerations. The series offers various package options including LCC and flatpack configurations to suit different mounting and environmental needs.

Replacement Considerations

Direct replacements include other parts within the 5962-89764 family such as 5962-8976401MXA or 5962-8976402MXA, differing primarily in package type or temperature grade. Verify pin compatibility and electrical specifications before substitution. Consult official Renesas documentation for qualified alternate sources.
