5962-9089904MYA

Overview

The Altera 5962-9089904MYA is a military-grade, high-speed dual-port static RAM component belonging to the 5962-89764 family. It features a memory configuration of 4K words by 8 bits with true dual-ported architecture allowing simultaneous access to the same location. The device operates asynchronously and supports battery backup for data retention at low voltages. It utilizes a single 5V power supply compatible with TTL logic levels and includes an automatic power-down feature controlled by chip enable signals to minimize standby power consumption.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent access to shared memory locations without internal hardware arbitration
• Fully asynchronous operation from either port designed for systems capable of external contention management or wait-state tolerance
• Military grade construction compliant with MIL-PRF-38535 QML standards ensuring reliability in harsh environments
• Automatic power down capability via chip enable control to achieve very low standby power modes

Applications

• High-speed data buffering in military avionics systems requiring concurrent read/write operations
• Real-time signal processing architectures where external arbitration mechanisms are implemented
• Battery-backed memory storage solutions for critical data retention in defense electronics
• Asynchronous communication interfaces demanding low-latency access without clock synchronization constraints

Procurement Notes

Verify the specific suffix MYA confirms the 48-pin Leadless Ceramic Chip Carrier package type. Confirm the part status as obsolete before procurement planning. Ensure compatibility with existing MIL-PRF-38535 quality requirements. Validate that system design accommodates the lack of internal arbitration for simultaneous port access. Check for lead-free compliance documentation if required by current assembly standards.

Selection Notes

Select this component when true dual-port functionality is required without internal arbitration overhead. Suitable for applications needing asynchronous access from multiple masters. Ideal for military specifications requiring QML certification. Consider the 48-pin LCC package constraints for board layout. Evaluate the need for external contention handling mechanisms in the system design.

Part Context

This part belongs to the 5962-89764 family of dual-port SRAMs manufactured under military specifications. It shares core architectural features with other variants in the series differing primarily in package options and temperature grades. The family is designed for high-reliability applications where concurrent memory access is critical. It represents a legacy solution for specialized military and aerospace memory requirements.

Replacement Considerations

Direct replacements include other 5962-89764 family variants such as 5962-8976401MYA through 5962-8976408MYA depending on specific package or temperature grade needs. Verify pinout compatibility and electrical characteristics match exactly. Cross-reference with current military qualified dual-port SRAM offerings if obsolescence is a concern.
