7005S25JG

Overview

The Renesas Electronics Corporation 7005S25JG is a high-speed 8K x 8 dual-port static RAM. It features true dual-ported memory cells allowing simultaneous reads of the same location. The device supports on-chip port arbitration logic and semaphore signaling for master/slave configurations. It operates asynchronously from either port with TTL-compatible single 5V power supply. The component includes automatic power-down features controlled by chip enable inputs.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access
• On-chip hardware support for semaphore signaling and interrupt flags
• Automatic low standby power mode via chip enable control
• TTL-compatible interface with single 5V power supply requirement

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port RAM combinations for 16-bit or wider word systems
• Battery backup applications requiring 2V data retention

Procurement Notes

Verify RoHS compliance status as specific listings indicate non-compliance. Confirm package type matches design requirements, typically 68-pin PLCC or PGA. Check moisture sensitivity level ratings before assembly. Ensure lead-free alternatives are considered if required by target market regulations. Validate temperature range specifications against operational environment needs.

Selection Notes

Select this component for applications requiring simultaneous independent access to shared memory locations. Suitable for systems needing hardware-based arbitration without external logic. Consider thermal performance within specified operating ranges. Verify voltage tolerance margins for stable operation in noisy environments.

Part Context

Part of the 7005 series dual-port SRAM family. Manufactured by Renesas Electronics Corporation, formerly IDT. Designed for high-speed asynchronous operations. Available in multiple package options including surface mount and through-hole variants. Supports industrial and commercial temperature ranges depending on suffix.

Replacement Considerations

Check for direct pin-compatible upgrades within the 7005L series. Verify electrical characteristics match original design constraints. Review package dimensions for mechanical fit. Confirm availability of newer generation components with improved efficiency.
