5962-8976401MXA

Overview

The 5962-8976401MXA is a military-grade dual-port static RAM component manufactured by Renesas Electronics. It implements a 4K x 8 memory organization with true dual-ported memory cells that permit simultaneous access to the same memory location from both ports. The device operates asynchronously and requires no clocks or refreshing for operation. It supports battery backup data retention at supply levels as low as 2V and functions on a single 5V power supply with TTL-compatible inputs and outputs.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations without internal hardware arbitration
• Fully asynchronous static circuitry eliminating the need for clock signals or periodic refresh cycles
• Battery backup capability maintaining data integrity at reduced voltage levels down to 2V
• TTL-compatible input and output interfaces allowing direct connection to standard logic systems

Applications

• Systems requiring external port arbitration for concurrent memory access
• Applications intolerant of wait states during memory operations
• Military and aerospace electronic assemblies compliant with MIL-PRF-38535 QML standards

Procurement Notes

Verify current availability status as this component may be obsolete. Confirm package type CPACK-48 compatibility with existing PCB footprints. Ensure design accounts for the lack of internal arbitration if implementing concurrent access protocols. Validate thermal requirements for the ceramic LCC package in final assembly.

Selection Notes

Select this component when system architecture mandates external arbitration for dual-port RAM contention. Suitable for designs requiring high-speed asynchronous access without clock synchronization overhead. Consider the 48-pin ceramic package constraints for board layout. Verify that the 5V supply requirement aligns with the target system power rails.

Part Context

This part belongs to the 5962-89764 series of dual-port SRAMs. It is classified under military-grade memory products compliant with MIL-PRF-38535. The device serves as a specialized memory solution for high-reliability applications where simultaneous read/write operations from two independent masters are required without internal conflict resolution mechanisms.

Replacement Considerations

Direct substitutes include other variants within the 5962-89764 family such as 5962-8976401MYA, which shares the same functional specifications but differs in package style. Cross-reference pinouts and electrical characteristics before substitution.
