7005S25G

Overview

The Renesas Electronics Corporation 7005S25G is a high-speed 64K-bit (8K x 8) dual-port static random-access memory (SRAM). It features asynchronous parallel interface with a 25 ns access time. The device operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. It utilizes true dual-ported memory cells allowing simultaneous reads from the same location. The component is housed in a 68-pin PGA package measuring 29.46x29.46 mm and supports an operating temperature range of 0°C to 70°C.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access by two ports
• On-chip hardware support for semaphore signaling and port arbitration logic
• Automatic low standby power mode controlled by chip enable signals
• TTL-compatible single 5V power supply operation

Applications

• Stand-alone 64K-bit dual-port RAM systems
• Master/Slave dual-port configurations for 16-bit or wider data bus expansion
• Systems requiring battery backup with 2V data retention capabilities

Procurement Notes

Verify component authenticity through authorized distributors as this part may be obsolete. Confirm package integrity and pin compatibility before integration. Check for RoHS compliance status as older variants may not meet current environmental standards. Ensure supply chain stability due to potential discontinuation risks associated with legacy SRAM families.

Selection Notes

Select this component when simultaneous bidirectional memory access is required without external arbitration overhead. Suitable for applications needing fast asynchronous data exchange between processors. Consider thermal management for surface mount installations. Verify that the 68-pin PGA footprint matches the target PCB design constraints.

Part Context

The 7005 series represents a family of high-speed dual-port SRAMs designed for complex data sharing applications. The 7005S25G specifically denotes the 25 nanosecond speed grade within the synchronous/asynchronous asynchronous variant lineup. It serves as a bridge between standard single-port memories and more complex FIFO structures, offering direct address/data line sharing.

Replacement Considerations

Public confirmed substitute part numbers include IDT7005S25G and IDT7005S25J8. These equivalents maintain identical functional specifications and pinouts. Verify package type differences such as PLCC versus PGA when substituting.
