7008S12J

Memory IC Overview

The Renesas 7008S12J 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/write ports for simultaneous data access. Key electrical specifications include a maximum access time of 12 nanoseconds and a write cycle time of 12 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package with J-leads, measuring 29.31mm x 29.31mm. It supports surface mount installation and functions across a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent and simultaneous read/write operations on separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing units
• Data logging applications requiring rapid sequential writes

Memory IC Procurement Notes

Verify the specific suffix designation, as the base model 7008S12 may have variants such as J or JI indicating package type. Confirm RoHS compliance status, as older batches may differ from current production runs. Check for End-of-Life notices, as this series has faced discontinuation announcements from the manufacturer. Ensure the required operating temperature range matches the specific suffix variant selected for your application environment.

Memory IC Selection Notes

Select this component when simultaneous independent access to memory data is critical for system performance. The 12ns speed class suits applications requiring low-latency data handling. Consider the PLCC package constraints regarding PCB space and thermal dissipation. Verify that the 5V logic levels align with the interfacing microcontroller or processor I/O standards without requiring level shifting.

Memory IC Part Context

This part belongs to the IDT/Renesas 7008 family of dual-port SRAMs, designed for high-performance computing and networking. The family offers various speed grades and packaging options to accommodate different design requirements. Renesas acquired the IDT product line, continuing support for these legacy high-speed memory solutions in industrial and communication equipment.

Memory IC Replacement Considerations

Direct pin-to-pin replacements are limited due to the specific 12ns speed grade and PLCC form factor. Evaluate other 7008 series variants like the 7008L20 if slower speeds are acceptable. Cross-reference with IDT-branded equivalents if available in inventory. Verify functional compatibility with any proposed substitute before integration.
