7005S25PFG

Overview

The Renesas Electronics Corporation 7005S25PFG is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It features an 8K x 8 organization, providing a total storage capacity of 64 kilobits. The component supports simultaneous independent access to the same memory location from two separate ports, facilitating efficient data exchange in master/slave configurations or standalone systems. It operates on a single 5V power supply with TTL-compatible I/O levels and includes built-in hardware support for semaphores and interrupt flags to manage bus arbitration.

Feature Summary

• True dual-ported memory architecture enabling simultaneous reads of identical locations
• On-chip hardware logic for semaphore signaling and port arbitration
• Asynchronous operation capability from either port without clock synchronization
• Automatic low-power standby mode controlled by chip enable signals

Applications

• Master/Slave dual-port RAM configurations for 16-bit or wider word systems
• High-speed data buffering in telecommunications equipment
• Real-time processing units requiring concurrent data access
• Industrial control systems utilizing asynchronous communication protocols

Procurement Notes

Verify component authenticity through authorized distributors as this part may be discontinued. Confirm package type and suffix codes match design requirements. Check for lead-free status and moisture sensitivity level compliance before assembly. Ensure supply chain stability due to potential end-of-life status.

Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. Suitable for applications needing fast asynchronous interfaces with standard 5V logic compatibility. Consider thermal management and power consumption specifications during system integration.

Part Context

Part of the 7005 series dual-port SRAM family offering various access times and package options. Designed for robust performance in industrial and commercial environments. Provides scalable memory solutions for complex embedded systems requiring high-speed data sharing between processors.

Replacement Considerations

Consult manufacturer documentation for direct pin-to-pin replacements. Verify electrical characteristics and timing parameters match original design constraints. Evaluate alternative packages if form factor changes are acceptable.
