7024L55JI8

Memory IC Overview

The Renesas Electronics Corporation 7024L55JI8 is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 4K words by 16 bits. The device features asynchronous parallel interface operation with an access time and write cycle time of 55 nanoseconds. It operates on a single 4.5V to 5.5V power supply and is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package measuring 29.31mm x 29.31mm.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access from two separate ports without external arbitration logic.
• Asynchronous operation allowing flexible timing control for both read and write cycles from either port.
• CMOS technology ensuring low power consumption while maintaining high-speed data transfer capabilities.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring concurrent data handling.
• Industrial control systems needing reliable volatile memory for real-time process data storage.
• Embedded computing modules utilizing parallel interfaces for legacy or specific protocol compatibility.

Memory IC Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations may indicate different temperature grades or packaging types. Confirm current production status, as this component family has faced discontinuation notices. Ensure compliance with RoHS directives relevant to your region before procurement. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Memory IC Selection Notes

Select this component when a 64Kb dual-port SRAM with 55ns speed is required in an 84-PLCC package. Compare against other 7024L series variants if faster access times like 15ns or 20ns are needed, noting that those parts may have different pinouts or electrical characteristics. Consider the operating temperature range; verify if the commercial grade meets system requirements or if industrial grade alternatives are necessary.

Memory IC Part Context

This part belongs to the Renesas 7024L series of dual-port SRAMs, originally developed by Integrated Device Technology (IDT). The series offers various speed grades and package options for different performance needs. The 7024L55 variant specifically targets applications where moderate speed is sufficient, balancing cost and performance. Renesas acquired IDT's memory assets, continuing support for these established products.

Memory IC Replacement Considerations

Publicly confirmed substitute part numbers for this specific component were not identified in available documentation. Users should consult official Renesas EOL notices for recommended obsolescence management strategies or direct replacements within the updated product portfolio.
