5962-9166205MYA

Overview

The Renesas Electronics Corporation 5962-9166205MYA is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 64 kilobits, organized to support parallel data access interfaces. The device features a maximum access time of 45 nanoseconds, ensuring rapid read and write operations for high-speed data processing applications. It is housed in an 84-pin Fine-Pitch Ball Grid Array (FPACK) package, designed for robust surface-mount assembly. The component is compliant with lead-free and RoHS standards, indicating adherence to environmental regulations for hazardous substances.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate controllers or processors.
• Asynchronous operation mode allowing flexible timing control without reliance on a global clock signal.
• Parallel interface design supporting direct connection to standard digital logic buses.

Applications

• High-performance embedded systems requiring fast data buffering between processing units.
• Telecommunications equipment utilizing asynchronous data transfer protocols.
• Industrial automation controllers needing reliable non-volatile-like temporary storage during power fluctuations.

Procurement Notes

Verify the specific datasheet revision and manufacturing lot details upon order confirmation. Ensure that the procurement channel provides traceability documentation consistent with aerospace or industrial grade requirements if applicable. Confirm that the 84-FPACK footprint matches the target printed circuit board layout exactly. Check for any specific handling instructions related to electrostatic discharge protection during installation.

Selection Notes

Select this component when system design requires true dual-port capability for concurrent data access by multiple masters. The 45 ns speed class is suitable for mid-range asynchronous interfaces where clock synchronization is not feasible. Consider the 84-FPACK package constraints regarding thermal dissipation and soldering profile compatibility with the assembly process. Evaluate pinout compatibility with existing reference designs before finalizing the bill of materials.

Part Context

This part belongs to Renesas' military-grade and high-reliability SRAM portfolio, often designated under the 5962 series format which indicates radiation-hardened or extended temperature range variants. The MYA suffix typically denotes specific packaging and material compliance attributes within the manufacturer's classification system. These components are engineered for environments demanding higher reliability than commercial grade parts.

Replacement Considerations

Direct cross-reference should be verified against the official Renesas replacement guide. Equivalent parts must match the 64Kbit density, dual-port functionality, 45 ns max access time, and 84-FPACK physical dimensions. Generic single-port SRAMs are not functionally equivalent due to the loss of concurrent access capability.
