7024S15JI

Memory IC Overview

The Renesas Electronics Corporation 7024S15JI 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 and write cycle time of 15 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package, measuring 29.31mm x 29.31mm. It supports an industrial operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two separate ports for high-throughput data handling.
• Includes on-chip hardware logic for port arbitration and semaphore signaling to manage concurrent access conflicts.
• Features automatic power-down functionality controlled by chip enable signals to minimize standby power consumption.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial automation controllers

Memory IC Procurement Notes

Verify the specific suffix designation against official documentation, as packaging variations such as tape-and-reel or tube configurations may exist within the product family. Confirm RoHS compliance status, as this specific part number indicates non-compliance with current environmental directives. Check for active discontinuation notices or product change notifications that may affect long-term availability or manufacturing origin. Ensure compatibility with existing board layouts regarding the 84-PLCC footprint dimensions.

Memory IC Selection Notes

Select this component when dual-port architecture is required for simultaneous bidirectional data transfer without external arbitration logic. The 15ns speed class suits applications demanding rapid memory access cycles. Consider the 84-PLCC package constraints for surface-mount assembly processes. Evaluate the 4Kx16 organization against system word width requirements to ensure optimal memory utilization without excessive addressing overhead.

Memory IC Part Context

This component belongs to the 7024S series of dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and packaging options to accommodate different performance and form-factor requirements. The 7024S15JI represents a specific speed bin and package configuration within this broader product line, designed for robust asynchronous memory applications.

Memory IC Replacement Considerations

Consult official substitution guides for compatible parts within the same series. Verify pinout compatibility and electrical specifications before replacing. Note that suffix changes may indicate packaging differences rather than functional alterations.
