7024S25JI8

Memory IC Overview

The Renesas Electronics Corporation 7024S25JI8 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 25 nanoseconds. It operates on a single power supply voltage ranging from 4.5 volts to 5.5 volts. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package, measuring 29.31mm by 29.31mm. It supports surface mount installation and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Provides independent read/write ports for simultaneous data access without bus contention
• Supports high-speed asynchronous operations with 25ns timing characteristics
• Designed for robust performance across extended industrial temperature environments

Memory IC Applications

• High-performance embedded systems requiring concurrent data handling
• Industrial control units operating in extreme thermal conditions
• Telecommunications infrastructure equipment demanding reliable volatile storage

Memory IC Procurement Notes

Verify the specific suffix JI8 to confirm the industrial temperature grade and tape-and-reel packaging configuration. Confirm RoHS compliance status as older variants may not meet current environmental directives. Check manufacturer discontinuation notices for availability constraints. Ensure the ordering part number matches the required lead frame and moisture sensitivity level specifications for your assembly process.

Memory IC Selection Notes

Select this component when dual-port functionality is required for complex data buffering tasks. Choose the 25ns speed grade for applications needing faster throughput than slower alternatives. Opt for the PLCC package if the design accommodates its specific footprint and pin pitch. Consider the industrial temperature rating for deployments outside standard commercial limits.

Memory IC Part Context

This part belongs to the Renesas 7024S series of dual-port SRAMs. It shares architectural similarities with other members like the 7024S25J but differs in temperature rating and packaging. The series is designed for applications requiring independent port access. It serves as a legacy solution for systems previously utilizing IDT-compatible memory architectures.
