7006S45FB

Overview

The Renesas 7006S45FB is a high-speed 16K x 8 Dual-Port Static RAM designed for stand-alone or master/slave configurations. It features true dual-ported memory cells allowing simultaneous reads of the same location, on-chip port arbitration logic, and hardware semaphore signaling. The device operates asynchronously from either port with TTL-compatible single 5V power supply and supports battery backup data retention at 2V. Available in 68-pin PLCC packages, it offers access times of 45 ns and functions within industrial temperature ranges.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared memory locations by two distinct ports.
• Integrated on-chip hardware support for semaphore signaling and automatic port arbitration logic to manage bus conflicts.
• Asynchronous operation capability from either port with low standby power mode controlled by chip enable signals.
• Battery backup functionality ensuring data retention at reduced voltage levels while maintaining standard operational integrity.

Applications

• Stand-alone 128K-bit dual-port memory systems
• Master/slave dual-port RAM combinations for 16-bit or wider word systems
• Industrial control applications requiring asynchronous data exchange between processors

Procurement Notes

Verify component authenticity through authorized distributors as counterfeit risks exist for legacy SRAM parts. Confirm package type matches design requirements since multiple pinouts are available within the family. Check end-of-life status notifications carefully, as discontinuation notices may affect long-term availability. Ensure voltage specifications align with system power rails before integration.

Selection Notes

Select this component when simultaneous read access to identical memory addresses is required without external arbitration circuitry. Choose the 7006 series over single-port alternatives for multi-processor architectures needing direct memory sharing. Verify that the asynchronous interface timing meets system clock constraints. Consider thermal performance if operating near maximum industrial temperature limits.

Part Context

The 7006 series represents Renesas' high-performance dual-port SRAM line derived from IDT heritage. These devices bridge legacy compatibility with modern multi-core processing needs. The specific model belongs to the broader family offering various access speeds and packaging options. This particular variant targets industrial environments requiring reliable data retention and robust signal integrity.

Replacement Considerations

IDT7006 variants serve as direct functional substitutes within the same product lineage. Cross-reference pinout compatibility when substituting between different package types like PLCC versus TQFP. Verify electrical parameters match exactly since speed grades vary across the series. Consult official obsolescence notices for discontinued manufacturing runs.
