5962-8976404MYA

Overview

The 5962-8976404MYA is a military-grade, high-speed 4K x 8 dual-port static RAM. It features true dual-ported memory cells allowing simultaneous access to the same location from either port. The device operates fully asynchronously and supports battery backup for data retention at voltages as low as 2V. It utilizes a TTL-compatible single 5V power supply with ±10% tolerance. An automatic power-down feature controlled by the chip enable signal allows on-chip circuitry to enter a very low standby power mode. This component complies with MIL-PRF-38535 QML requirements.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations without internal arbitration.
• Fully asynchronous operation from either port, eliminating wait states for systems designed for external contention handling.
• Battery backup capability ensuring data retention at supply levels as low as 2V.
• Compliance with MIL-PRF-38535 QML standards for military-grade reliability.

Applications

• Systems requiring high-speed data exchange without on-chip hardware port arbitration
• Military and aerospace applications demanding compliance with MIL-PRF-38535 QML standards
• Real-time control systems where external arbitration logic manages simultaneous port access

Procurement Notes

Verify the specific suffix MYA against official Renesas or Intersil documentation to confirm package type and temperature grade. Confirm current product status as obsolete in distributor databases. Ensure compatibility with existing system voltage levels and interface requirements before procurement.

Selection Notes

Select this component for applications requiring true dual-port functionality with asynchronous access. Consider the 48-pin ceramic LCC package availability. Evaluate system design for external arbitration capabilities since on-chip arbitration is not provided. Verify MIL-PRF-38535 QML qualification needs.

Part Context

This part belongs to the IDT 7134 series of dual-port SRAMs. It is manufactured under the Renesas Electronics Corporation brand, formerly associated with Integrated Device Technology (IDT). The 5962 prefix indicates it is a military-grade part number managed through the Defense Logistics Agency.

Replacement Considerations

Check for direct cross-references within the IDT 7134 family. Verify equivalent military-grade dual-port SRAMs from other manufacturers if the original part is unavailable. Ensure pinout and electrical specifications match exactly.
