5962-9215602MXA

Overview

The Microsemi Corporation 5962-9215602MXA is a high-reliability, military-grade dual-port static random-access memory (DPRAM). It features an 8K x 16-bit memory organization, providing a total capacity of 128 kilobits. The device utilizes true dual-ported memory cells, enabling simultaneous independent access to the same memory location from both ports without conflict. It operates on a single +5V power supply with a tolerance of ±10%. The component supports fully asynchronous operation and includes hardware support for semaphore signaling between ports. It is designed for applications requiring high-speed data buffering and protocol conversion in demanding environments.

Feature Summary

• True dual-ported architecture allowing simultaneous reads of the same memory location
• Hardware support for semaphore signaling and port arbitration logic
• TTL-compatible interface with single +5V power supply operation
• Automatic power-down feature controlled by chip enable for low standby power

Applications

• High-speed data buffering in communication systems
• Protocol conversion interfaces in aerospace and defense electronics
• Master/slave dual-port RAM configurations for 32-bit or wider data bus systems

Procurement Notes

Verify the specific suffix MXA against official Microsemi documentation to confirm package type and temperature range. Confirm current availability status as military-grade components may have limited stock or long lead times. Ensure compliance with MIL-PRF-38535 requirements if applicable to your design. Check for any product change notices or end-of-life notifications prior to finalizing procurement plans.

Selection Notes

Select this component when simultaneous bidirectional access to shared memory is required without external arbitration logic. Consider the 84-pin ceramic PGA package for radiation-hardened or high-reliability applications. Evaluate power consumption requirements, noting the automatic power-down feature for standby modes. Ensure system voltage matches the single +5V specification with ±10% tolerance.

Part Context

This part belongs to the 5962-92156 series of dual-port SRAMs manufactured by Microsemi (now part of Microchip Technology). These devices are designed for high-reliability applications in aerospace, defense, and industrial markets. The 5962 prefix indicates a military-grade qualification under MIL-PRF-38535 standards. The series offers various capacities and speeds tailored for complex data handling tasks.

Replacement Considerations

Check for direct cross-reference parts within the Microsemi/Microchip portfolio that share the same pinout and electrical characteristics. Verify compatibility with existing board layouts and software drivers. Consider newer generations of DPRAMs if improved performance or lower power consumption is needed, ensuring they meet the same reliability standards.
