7008S12PF8

Memory IC Overview

The Renesas 7008S12PF8 is a high-speed, 512Kb (64K x 8) dual-port static RAM featuring asynchronous parallel interface operation. It provides a 15 ns access time and operates on a single 5V power supply within the 4.5V to 5.5V range. The device supports simultaneous independent reads from both ports and includes hardware semaphore signaling for port arbitration. It is housed in a 100-pin TQFP package with an industrial temperature rating of 0°C to 70°C.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent read access to the same memory location from both ports without conflict.
• On-chip hardware support for semaphore signaling and automatic port arbitration logic to manage data integrity during concurrent operations.
• Asynchronous operation allowing flexible timing control from either port, compatible with TTL-level inputs and outputs.

Memory IC Applications

• High-speed data buffering in telecommunications equipment requiring low-latency packet storage.
• Master/slave configurations in 16-bit or wider data bus systems for expanded memory addressing.
• Real-time signal processing applications needing immediate data availability from multiple processors.

Memory IC Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as older batches may not meet current environmental standards. Check for moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure voltage supply stability within the specified 4.5V to 5.5V range to prevent operational faults.

Memory IC Selection Notes

Select this component when true dual-port independence is required for simultaneous read operations. Choose over single-port alternatives if concurrent processor access to shared data is necessary. Consider the 15 ns speed for applications demanding rapid data retrieval. Verify package compatibility with existing PCB footprints for the 100-TQFP form factor.

Memory IC Part Context

Part of the Renesas 7008S series, designed for high-performance embedded systems. This series emphasizes reliability in industrial environments with robust arbitration features. The 7008S12 variant specifically targets applications needing faster cycle times compared to slower variants in the family.

Memory IC Replacement Considerations

Direct substitutes include other 512Kb dual-port SRAMs with similar pinouts and speeds. Verify electrical compatibility regarding voltage levels and access times before substitution. Cross-reference with IDT equivalents if sourcing from legacy inventories.
