5962-8866515UA

Memory IC Overview

The Renesas Electronics Corporation 5962-8866515UA is a high-speed 2K x 16 Dual-Port Static RAM designed for military-grade applications compliant with MIL-PRF-38535 QML. It features true dual-ported memory cells allowing simultaneous access to the same location, fully asynchronous operation from either port, and on-chip port arbitration logic. The device supports battery backup data retention at 2V and operates on a single 5V (±10%) TTL-compatible power supply. It is available in a 68-pin Flatpack package.

Memory IC Feature Summary

• True dual-ported memory cells enable simultaneous access of the same memory location by both ports.
• On-chip port arbitration logic manages bus conflicts without external discrete logic.
• Versatile write control allows separate management of lower and upper bytes per port.
• Supports battery backup operation for data retention during power loss.

Memory IC Applications

• Multiprocessing systems requiring high-speed shared memory
• Military-grade embedded storage solutions
• Master/Slave dual-port RAM configurations for expanded data bus widths

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to military compliance requirements. Confirm package integrity for the 68-pin Flatpack variant. Check for end-of-life status as this specific suffix may be obsolete. Ensure environmental specifications match operational needs.

Memory IC Selection Notes

Select this component when simultaneous independent access to shared memory is required in harsh environments. Consider the 68-pin Flatpack form factor for specific board layout constraints. Evaluate compatibility with existing TTL-compatible interfaces and 5V power domains before integration.

Memory IC Part Context

This part belongs to the IDT 7133/43 family of dual-port SRAMs. It is manufactured under the 5962 prefix indicating military-grade qualification. The 15UA suffix typically denotes the 68-pin ceramic flatpack package variant within this product line.

Memory IC Replacement Considerations

Direct substitutes include other parts from the 5962-88665 series with compatible pinouts. Verify functional equivalence for master/slave expansion capabilities. Cross-reference MIL-PRF-38535 compliance for critical military applications.
