7024L20J8

Memory IC Overview

The Renesas Electronics Corporation 7024L20J8 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 20 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.

Memory IC Applications

• High-speed data buffering in telecommunications equipment.

Memory IC Procurement Notes

This component is officially designated as End-of-Life (EOL) by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or surplus channels. Procurement should prioritize authentic sources to avoid counterfeit parts, as discontinuation often increases reliance on secondary markets. Confirm RoHS compliance status and specific lot dates before acquisition.

Memory IC Selection Notes

Engineers replacing this part must evaluate pin-compatible alternatives within the same family that meet the 20 ns access time requirement. Verify that substitute components support the required 4K x 16 organization and dual-port functionality. Ensure the replacement package matches the 84-PLCC form factor for existing board layouts without redesigning the footprint.

Memory IC Part Context

The 7024L20J8 belongs to the 7024L series of high-performance dual-port SRAMs manufactured by Renesas Electronics. This series is characterized by fast cycle times and low power consumption, targeting applications requiring reliable, high-speed memory sharing between multiple masters in embedded systems.

Memory IC Replacement Considerations

Official substitutes include IDT7024L20J8. Verify functional equivalence regarding timing parameters and pinout compatibility before integration into existing designs.
