7024L45J8

Memory IC Overview

The Renesas Electronics Corporation 7024L45J8 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 a maximum access time of 45 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-PLCC package measuring 29.31x29.31 mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

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

Verify the specific suffix J8 against official documentation to confirm the tape-and-reel packaging configuration, as this variant differs from tube-packaged equivalents. Confirm RoHS compliance status, as current records indicate non-compliance. Check for end-of-life notices or discontinuance notifications prior to procurement planning. Ensure the supplier provides valid traceability documents for this discontinued component series.

Memory IC Selection Notes

Select this component when a 64Kb dual-port SRAM with 45ns speed is required in an 84-pin PLCC package. Compare against other variants in the 7024L45 family regarding packaging type and temperature rating. Verify that the 4.5V to 5.5V supply range matches the system design constraints. Consider the availability of replacement parts due to the discontinued status of this specific part number.

Memory IC Part Context

This component belongs to the 7024L45 series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options. The 7024L45J8 specifically denotes the 45ns speed grade in a tape-and-reel format. Other members include different access times and physical packages, such as the 7024L45JI or 7024L45GB, which share similar electrical characteristics but differ in mechanical form factors.
