7025L55GB

Memory IC Overview

The Renesas Electronics Corporation 7025L55GB is a dual-port static random-access memory (SRAM) device belonging to the 7025L series. It features an 8K x 16 memory organization, providing a total storage capacity of 128 kbit. The component supports asynchronous parallel interface operation with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in an 84-pin PGA package.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent read/write operations from separate ports
• Asynchronous operation allowing flexible timing control for both master and slave configurations
• Integrated hardware support for semaphore signaling and port arbitration logic

Memory IC Applications

• High-speed data buffering in multiprocessor systems
• Cache memory implementation in embedded controllers
• Data storage in industrial automation equipment

Memory IC Procurement Notes

Verify RoHS compliance status as documentation indicates non-compliance. Confirm package integrity upon receipt due to potential handling sensitivity. Check for discontinuation notices or product change notifications prior to final design approval. Ensure supply chain stability given the component's availability constraints.

Memory IC Selection Notes

Select this part when a 55 ns access speed meets system requirements. Choose the 84-pin PGA package for through-hole mounting needs. Consider alternative speeds if faster performance is required. Verify temperature range suitability for the specific application environment before integration.

Memory IC Part Context

This component is part of the Renesas 7025 family of high-speed dual-port SRAMs. It serves as a standalone 128K-bit memory solution or can be combined in master/slave configurations for wider data buses. The device supports battery backup operation for data retention.
