5962-8976408MYA

Overview

The 5962-8976408MYA is a military-grade, high-speed 4K x 8 Dual-Port Static RAM manufactured by Renesas Electronics Corporation under the IDT 7134 designation. It features true dual-ported memory cells allowing simultaneous access to the same location without on-chip arbitration. The device operates asynchronously from either port and supports battery backup with data retention down to 2V. It utilizes a TTL-compatible single 5V power supply (±10%) and includes an automatic power-down feature controlled by chip enable signals for low standby power. This component complies with MIL-PRF-38535 QML requirements.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations
• Military-grade qualification compliant with MIL-PRF-38535 QML standards
• Asynchronous operation supporting systems requiring external arbitration or contention tolerance
• Battery backup capability ensuring data retention at voltages as low as 2V

Applications

• Systems requiring high-speed data buffering without hardware port arbitration
• Military and aerospace electronic assemblies demanding radiation-hardened reliability
• Parallel processing architectures utilizing external bus arbitration mechanisms
• Critical data storage applications necessitating battery-backed retention capabilities

Procurement Notes

Verify that the specific suffix MYA corresponds to the 48-pin Ceramic LCC package configuration. Confirm compliance with current MIL-PRF-38535 specifications. Ensure procurement channels are authorized for QML qualified components. Validate environmental testing records if required for mission-critical deployment. Check for obsolescence status updates prior to finalizing acquisition.

Selection Notes

Select this component when system design requires true simultaneous dual-port access without internal arbitration logic. Suitable for environments where external contention handling is preferred over integrated solutions. Ideal for applications mandating MIL-PRF-38535 QML certification. Consider when battery backup support down to 2V is necessary for data preservation during power transitions.

Part Context

This part belongs to the IDT 7134 family of high-speed dual-port SRAMs. It represents a specialized subset designed for rigorous military and space applications. The 5962 prefix indicates a direct buy or military-specific variant managed through Defense Logistics Agency specifications. It serves as a critical interconnect element in complex parallel computing systems.

Replacement Considerations

Direct substitutes include other 5962-89764 variants with different package options such as SB or MXA suffixes. Cross-reference with generic IDT 7134 equivalents only if military qualification waivers are permissible. Verify pinout compatibility before substituting with non-QML commercial grade parts.
