7005L25G

Overview

The Renesas Electronics Corporation 7005L25G is a dual-port static random-access memory (SRAM) device with a storage capacity of 64 kbit, organized as 8k x 8. It features an asynchronous parallel interface with a maximum access time of 25 ns. The component operates on a single 5V power supply ranging from 4.5 V to 5.5 V and supports through-hole installation in a PGA-68 package. It functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• True dual-ported memory cells enable simultaneous independent reads and writes from either port without conflict.
• On-chip hardware support for semaphore signaling facilitates master/slave configurations and port arbitration.
• Integrated interrupt flag logic provides status indication for busy conditions or write cycles.

Applications

• High-speed data buffering in communication systems requiring concurrent host and peripheral access
• Master/slave dual-port RAM configurations for expanding data bus widths in 16-bit or larger systems
• Industrial control applications utilizing asynchronous parallel interfaces for real-time data logging

Procurement Notes

Verify the specific suffix G indicates the PGA-68 through-hole package variant. Confirm RoHS compliance status as documentation may vary by production batch. Check for end-of-life notifications or discontinuation notices prior to final design approval. Ensure voltage levels match the 4.5V to 5.5V requirement for reliable operation.

Selection Notes

Select this component when true dual-port functionality is required for simultaneous independent access. Compare against single-port alternatives if concurrent operations are unnecessary. Verify package compatibility with existing PCB footprints for PGA-68 through-hole mounting. Consider thermal performance within the specified commercial temperature range during system integration.

Part Context

This part belongs to the Renesas 7005 series of high-speed dual-port SRAMs. The series offers various access times and packaging options to suit different system requirements. The 7005L25G specifically targets commercial temperature applications with a 25 ns speed grade.

Replacement Considerations

Cross-reference with IDT7005L25G for pin-compatible alternatives. Verify electrical specifications and package dimensions before substitution. Consult manufacturer documentation for any functional differences between legacy and current production runs.
