7133SA70GB

Overview

The Renesas Electronics Corporation 7133SA70GB is a 32Kb (2K x 16) CMOS dual-port static random access memory. It features asynchronous parallel interface operation with a maximum access time of 70 ns. The device operates on a single 5V power supply within the 4.5V to 5.5V range and supports independent read/write operations on both ports. It is housed in a 68-pin PGA package designed for through-hole mounting.

Feature Summary

• Dual-port architecture enabling simultaneous independent access by two processors
• Asynchronous parallel interface for flexible system integration
• Single 5V power supply operation compatible with standard logic levels

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring dual-processor access

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity and pin configuration against original specifications before integration into new designs.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access. Ensure the design accommodates the 68-pin PGA through-hole package constraints. Verify that the 70 ns access speed meets system timing requirements and that the 5V supply voltage aligns with existing power rails.

Part Context

This component belongs to the 7133SA series of dual-port SRAMs manufactured by Renesas Electronics. The series provides scalable memory solutions for applications requiring high-speed data sharing between multiple masters without external arbitration overhead.
