5962-8687512YA

Memory IC Overview

The 5962-8687512YA is a high-speed 1K x 8 dual-port static RAM designed for use as a standalone 8-bit device or as a slave unit in master/slave configurations. It features asynchronous operation from either port, allowing simultaneous access to the same memory location through true dual-ported memory cells. The component supports battery backup with 2V data retention and operates on a single 5V (±10%) power supply compatible with TTL logic levels.

Memory IC Feature Summary

• True dual-ported memory cells enable simultaneous independent access to identical memory locations by both ports without conflict.
• Versatile control mechanisms allow separate write management for lower and upper bytes of each port, facilitating flexible data bus expansion.
• On-chip port arbitration logic simplifies system design by supporting master/slave architectures for wider data buses without discrete logic.
• Fully asynchronous operation ensures compatibility with various timing requirements across different system interfaces.

Memory IC Applications

• High-speed data buffering in parallel processing systems
• Master/slave dual-port RAM configurations for expanded memory width
• Real-time data acquisition applications requiring simultaneous read/write access

Memory IC Procurement Notes

Verify the specific suffix code against official Renesas documentation to confirm exact speed grade and package variant. Ensure environmental compliance matches project requirements. Confirm availability status directly with authorized distributors as military-grade components may have limited stock. Validate pinout compatibility if replacing existing designs.

Memory IC Selection Notes

Select this component when simultaneous bidirectional access to shared memory is required without external arbitration hardware. Ideal for systems needing 8-bit wide data paths with high-speed asynchronous interfaces. Consider master/slave pairing options if 16-bit or wider data throughput is necessary for the application architecture.

Memory IC Part Context

This part belongs to the 5962-86875 family of dual-port SRAMs, which includes variants like the 5962-8687504YA and 5962-8687512YA. These devices are characterized by their military-grade reliability and compliance with MIL-PRF-38535 standards, offering robust performance in demanding industrial and aerospace environments.

Memory IC Replacement Considerations

Check for direct equivalents within the 5962-86875 series such as 5962-8687504YA for similar functionality. Verify that any substitute maintains the same 1K x 8 density, 5V operation, and asynchronous interface characteristics to ensure seamless integration into existing master/slave configurations.
