7008S12J8

Memory IC Overview

The Renesas Electronics Corporation 7008S12J8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a total storage capacity of 512 kilobits, organized as 64K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 12 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 operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on both ports
• Asynchronous parallel interface supporting high-speed data transfer
• Compact surface-mount packaging suitable for automated assembly processes

Memory IC Applications

• High-performance embedded systems requiring fast local memory
• Network infrastructure equipment needing rapid data buffering
• Industrial control systems utilizing parallel memory interfaces

Memory IC Procurement Notes

Verify current availability status as this component may be discontinued or subject to end-of-life notices. Confirm RoHS compliance requirements against specific project standards, noting that some variants in this series have different environmental classifications. Ensure the 84-PLCC package dimensions match the target PCB footprint exactly before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent processor access without arbitration overhead. Consider the 12ns access speed for timing-critical applications within the commercial temperature range. Evaluate the 84-PLCC package constraints against available board space and soldering capabilities compared to alternative pin-count packages.

Memory IC Part Context

This part belongs to the Renesas 7008 series of dual-port SRAMs, which offers various speed grades and package options. The series is designed for applications requiring independent port access. Other members include variants with different access times such as 15ns or 35ns, and different package types like TQFP. This specific model represents a mid-speed option in the PLCC form factor.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements within the same 7008 family, such as the 7008L15JG8 or 7008S35J8, depending on whether slower speeds are acceptable. Verify if newer generation components from Renesas offer equivalent functionality in modern packages.
