7024L55J8

Memory IC Overview

The Renesas Electronics Corporation 7024L55J8 is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kilobits organized as 4K words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-lead Plastic Leadless Chip Carrier (PLCC) package measuring 29.31x29.31 mm.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous operation allowing flexible timing control without external clock synchronization
• CMOS technology providing low power consumption characteristics suitable for battery-operated applications

Memory IC Applications

• High-speed data buffering between microprocessors and peripheral devices
• Cache memory implementation in embedded computing systems
• Data logging and temporary storage in industrial automation controllers

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential obsolescence status. Confirm RoHS compliance and moisture sensitivity level requirements for your assembly process. Check for specific ordering suffixes that may indicate package variations or temperature ranges. Ensure compatibility with existing PCB footprints and design rules before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Compare access times against system timing constraints to ensure the 55ns specification meets performance needs. Evaluate package dimensions against available board space. Consider alternative parts if single-port suffices or if lower power consumption is critical for the application.

Memory IC Part Context

This part belongs to the 7024L series of dual-port SRAMs manufactured by Renesas Electronics. The series typically offers various speed grades and packaging options to suit different design requirements. These components are commonly used in legacy systems or specialized industrial equipment where proven reliability and established interfaces are preferred over newer technologies.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include IDT7024L55J8, which represents the same device under the Integrated Device Technology branding prior to acquisition. Verify pinout compatibility and electrical specifications match exactly before substitution.
