7133SA35GB

Overview

The Renesas Electronics Corporation 7133SA35GB is a dual-port asynchronous static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 2k x 16 bits. The device features a parallel interface with a maximum access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 68-PGA package measuring 29.46x29.46 mm.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation for flexible system integration without clock synchronization
• CMOS technology ensuring low power consumption during standby and active states

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Real-time data logging in industrial control applications

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm RoHS compliance status as historical records indicate non-compliance for this specific variant. Check moisture sensitivity level handling requirements prior to assembly. Validate package dimensions against PCB footprint specifications to ensure mechanical compatibility.

Selection Notes

Select this component when independent dual-processor access to shared memory is required. Ensure the design accommodates the 68-PGA package constraints and 35 ns timing requirements. Verify that the system voltage aligns with the 4.5 V to 5.5 V operating range. Consider end-of-life status if long-term production support is critical for the application lifecycle.

Part Context

This part belongs to the Renesas 7133SA series of dual-port SRAMs. It shares architectural similarities with other variants like the 7133SA35J and 7133SA35PFG, differing primarily in package type. The series is designed for high-performance memory applications requiring concurrent read/write operations from separate ports.

Replacement Considerations

Direct substitutes include IDT7133SA35GB. Verify pinout compatibility and electrical parameters before substitution.
