5962-9166203MYA

Overview

The 5962-9166203MYA is a dual-port static random access memory (SRAM) manufactured by Renesas Electronics. It features a storage capacity of 64 kbit, organized as 4K x 16 bits. The device utilizes a parallel interface and operates on a single 5V power supply with a voltage range of 4.5 V to 5.5 V. It is housed in an 84-pin PGA package designed for surface mount technology. The component supports asynchronous operation and includes battery backup functionality for data retention.

Feature Summary

• True dual-ported architecture allowing simultaneous independent access to the same memory location from both ports without wait states.
• Asynchronous operation compatible with TTL logic levels, simplifying system integration and control.
• Battery backup capability ensures data retention at low voltage levels, supporting continuous operation during power transitions.

Applications

• High-speed data buffering in systems requiring concurrent read/write operations.
• Military-grade embedded applications compliant with MIL-PRF-38535 standards.
• Real-time control systems where contention handling is managed externally.

Procurement Notes

This component is classified as obsolete or end-of-life. Verify availability through authorized distributors or surplus channels. Confirm that the specific suffix MYA corresponds to the required ceramic LCC package variant. Ensure compliance with RoHS directives if applicable, as older military-grade parts may have different environmental certifications. Validate lead times and authenticity due to limited production status.

Selection Notes

Select this part for designs requiring true dual-port SRAM with high-speed asynchronous access. It is suitable for applications needing simultaneous port access without internal arbitration logic. Consider the PGA package constraints and thermal requirements. Evaluate if the 4K x 16 organization meets address and data width needs. Compare against newer dual-port alternatives if long-term supply assurance is critical.

Part Context

The 5962-9166203 series belongs to Renesas' line of radiation-hardened and military-grade memory components. These parts are designed for harsh environments and high-reliability applications. The 5962 prefix indicates a Defense Logistics Agency (DLA) specification number, often associated with QML qualified devices. This specific model represents a legacy dual-port SRAM solution within the broader portfolio of high-performance memory products.

Replacement Considerations

Verify direct pin-to-pin replacements such as the IDT 7134 series equivalents. Check for updated Renesas dual-port SRAM models with similar density and interface characteristics. Ensure any substitute maintains the required military temperature range and package type. Confirm that the replacement supports the necessary battery backup and asynchronous timing specifications.
