7005L25J

Overview

The Renesas Electronics Corporation 7005L25J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features an asynchronous parallel interface 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 a 68-pin Plastic Leadless Chip Carrier (PLCC) package measuring 24.21mm x 24.21mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Feature Summary

• Supports simultaneous independent read/write operations at two distinct ports
• Provides high-speed asynchronous data transfer via parallel interface
• Utilizes standard CMOS technology for low power consumption

Applications

• High-performance embedded systems requiring fast local memory
• Network infrastructure equipment such as routers and switches
• Industrial control systems needing reliable volatile storage

Procurement Notes

Verify RoHS compliance status carefully, as this specific part number may be non-compliant or obsolete. Confirm the exact package variant and suffix against current manufacturer documentation before integration. Check for moisture sensitivity level requirements during handling and storage. Ensure replacement components are sourced from authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. The 25ns speed suits applications demanding rapid data exchange without complex synchronization. Consider the PLCC package constraints for PCB layout. Evaluate alternative packages if higher pin counts or different thermal profiles are needed for the specific enclosure design.

Part Context

This device belongs to the IDT 7005 series of dual-port SRAMs, widely used in telecommunications and networking. The 'L' suffix typically denotes the leaded PLCC package option within the family. These parts serve as critical buffer memory in high-throughput data paths where latency must be minimized.
