7005L45JI

Overview

The Renesas Electronics Corporation 7005L45JI is a static random access memory component featuring an 8K x 8 organization and a total storage capacity of 64 kbit. It operates as an asynchronous dual-port RAM with a parallel interface and a maximum access time of 45 ns. The device supports a supply voltage range from 4.5 V to 5.5 V, with a maximum power supply current of 210 mA. It functions within a commercial temperature range of 0°C to +70°C and utilizes a 68-PLCC surface-mount package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for straightforward integration into standard logic systems
• Single 5V power supply operation compatible with standard CMOS logic levels

Applications

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

Procurement Notes

Verify the specific suffix JI against official datasheets to confirm package type and pinout compatibility. Confirm RoHS compliance status as older variants may not meet current environmental standards. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans. Ensure supplier documentation matches the exact manufacturer part number to avoid counterfeit risks.

Selection Notes

Select this component when a 64 kbit dual-port SRAM with 45 ns access speed is required. Compare against other 7005L series variants if different access times or package styles are needed. Verify that the 68-PLCC footprint fits the target PCB layout constraints. Ensure the operating voltage range aligns with the system's power delivery network.

Part Context

This part belongs to the Renesas 7005L series of dual-port static random access memories. These components are designed for applications requiring high-speed data exchange between two independent processors or buses. The series typically offers various access speeds and package options to suit different performance and space requirements.

Replacement Considerations

Consult official Renesas documentation for verified cross-reference parts. Ensure any substitute maintains the same 8K x 8 organization, 45 ns access time, and 68-PLCC package. Verify pin-to-pin compatibility and electrical specifications before replacement.
