7007S25J8

Memory IC Overview

The Renesas Electronics Corporation 7007S25J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 256 kilobits, organized as 32K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-pin PLCC package.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous parallel interface for straightforward integration into standard digital logic designs
• High-speed data retrieval capabilities suitable for performance-critical memory applications

Memory IC Applications

• Data buffering in high-speed communication interfaces
• Cache memory implementation in embedded processing systems
• FIFO buffer applications requiring independent read/write ports

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to discontinuation status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current environmental directives. Validate package integrity upon receipt, ensuring no physical damage to the PLCC leads before soldering operations commence.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. Ensure system power supplies remain stable within the 4.5V to 5.5V operating range. Consider thermal management requirements associated with the specified package type during PCB layout design to maintain reliable long-term operation under load.

Memory IC Part Context
