7024S17JI8

Memory IC Overview

The Renesas Electronics Corporation 7024S17JI8 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 and write cycle time of 17 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package, specifically identified as 84-PLCC with dimensions of 29.31mm by 29.31mm.

Memory IC Feature Summary

• Provides independent read/write access to two distinct ports for simultaneous data operations without external arbitration logic.
• Supports high-speed asynchronous data transfer with a 17 nanosecond access time for rapid system response.
• Designed for surface-mount installation using a compact 84-lead PLCC package suitable for dense circuit board layouts.

Memory IC Applications

• High-performance computing systems requiring fast data buffering
• Telecommunications equipment utilizing parallel memory interfaces
• Industrial control systems operating in extended temperature environments

Memory IC Procurement Notes

Verify the specific suffix designation carefully during procurement, as packaging variations such as tape-and-reel configurations exist within the same base model family. Confirm RoHS compliance status, as this specific variant may not meet current environmental standards. Check for active discontinuation notices or end-of-life notifications prior to finalizing orders, as availability may be limited. Ensure that the required moisture sensitivity level handling procedures are followed upon receipt to prevent package damage during assembly processes.

Memory IC Selection Notes

Select this component when a design requires true dual-port functionality with independent address and data buses for each port. The 17 nanosecond speed class is suitable for applications demanding low-latency memory access. Consider the 84-PLCC package constraints regarding board space and thermal dissipation capabilities. Verify that the system power supply can maintain stability within the 4.5V to 5.5V range under all load conditions to ensure reliable operation across the specified temperature spectrum.

Memory IC Part Context

This part belongs to the Renesas 7024S series of dual-port SRAM devices. The series offers various speed grades and organizational formats to accommodate different system performance requirements. The 7024S17 variant represents a specific speed bin within this lineup, distinguished by its 17 nanosecond access time specification compared to slower alternatives in the same product family.

Memory IC Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Cross-reference pin compatibility and electrical specifications before implementing any alternative components in existing designs.
