7025L20JI

Memory IC Overview

The Renesas Electronics Corporation 7025L20JI is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 128 kbit, organized as 8k words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 20 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in an 84-PLCC package. The component is designed for industrial temperature ranges, functioning reliably between -40°C and +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array from two separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications

Memory IC Procurement Notes

Verify the specific suffix 'JI' against current manufacturer documentation to confirm package type and environmental rating. Check for product discontinuation notices or lifecycle status updates prior to finalizing procurement plans. Ensure compatibility with existing board layouts regarding the 84-PLCC footprint and pin configuration.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations without external arbitration logic. The 20 ns speed suits high-frequency bus interfaces. Consider the 84-PLCC package constraints for PCB space and thermal management requirements in enclosed industrial enclosures.

Memory IC Part Context

This part belongs to the 7025L series of dual-port SRAMs from Renesas. These devices are engineered for applications requiring high bandwidth and low latency. The series typically offers various access speeds and packaging options to accommodate different system performance needs and physical design constraints.

Memory IC Replacement Considerations

Cross-reference with IDT7025L20JI for potential functional equivalence. Verify pinout compatibility and electrical specifications before substitution. Confirm availability and lifecycle status of alternative sources.
