7024L25J8

Memory IC Overview

The 7024L25J8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. 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 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-pin Plastic Leadless Chip Carrier (PLCC) package measuring 29.31x29.31 mm. The component is rated for commercial temperature ranges from 0°C to 70°C.

Memory IC Feature Summary

• Supports independent simultaneous read/write operations at both Port A and Port B without bus contention
• Provides dedicated busy output signals to indicate port availability during active write cycles
• Utilizes asynchronous control logic for straightforward integration into existing parallel bus architectures

Memory IC Applications

• Real-time data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller applications
• Data storage in telecommunications equipment requiring low-latency access

Memory IC Procurement Notes

Verify the specific suffix J8 confirms the 84-PLCC package configuration and lead type. Confirm RoHS compliance status as older variants may not meet current environmental directives. Check manufacturer discontinuation notices for lifecycle status. Ensure design-in compatibility with 5V logic levels and PLCC footprint dimensions.

Memory IC Selection Notes

Select this component when dual-port independence is required for concurrent processor access. Compare access times against system clock requirements to ensure 25 ns meets latency needs. Verify package compatibility with PCB assembly processes for PLCC components. Consider thermal dissipation characteristics within the specified operating temperature range.

Memory IC Part Context

This part belongs to the 7024L series of dual-port SRAMs, offering non-volatile-like concurrency through true dual-port architecture. It serves as a bridge between fast processors and slower peripheral devices. The series is characterized by high-speed parallel access and robust data integrity mechanisms.
