7008L35J8

Memory IC Overview

The Renesas Electronics Corporation 7008L35J8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a total storage capacity of 512 kilobits, organized as 64K words by 8 bits. The device features independent read and write ports, allowing simultaneous access operations without conflict. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum access time of 35 nanoseconds. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package with dimensions of 29.31mm x 29.31mm. It is designed for surface mount installation and functions reliably across a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through separate master and slave ports
• Integrates hardware-based arbitration mechanisms including semaphores, interrupts, and busy flags
• Enables flexible system configuration as either standalone memory or combined master/slave units

Memory IC Applications

• High-performance data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network routing infrastructure
• Real-time processing modules in embedded computing platforms

Memory IC Procurement Notes

Verify the specific suffix JG8 against the official datasheet to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status as regulatory requirements vary by region and manufacturing date. Check for End-of-Life notices or Product Change Notifications that may affect long-term availability. Ensure the procurement source provides valid traceability documentation for quality assurance purposes.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required without external arbitration logic. The 35ns access speed suits applications needing moderate throughput with low latency. Consider the 84-pin PLCC package constraints for PCB layout density. Evaluate power consumption at 5V operation against thermal management capabilities in the target enclosure design.

Memory IC Part Context

This part belongs to the IDT 7008 series of dual-port SRAMs, originally developed by Integrated Device Technology before its acquisition by Renesas. The series is characterized by its robust hardware arbitration features, distinguishing it from standard single-port memories. It serves as a bridge between high-speed processors and slower peripheral devices in complex digital architectures.
