7133SA25G

Overview

The Renesas Electronics Corporation 7133SA25G is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 2K x 16 bits. The device features an asynchronous parallel interface with a maximum access time of 25 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. The component is designed for commercial temperature environments ranging from 0°C to +70°C.

Feature Summary

• Supports simultaneous independent read and write operations through two distinct port structures
• Utilizes CMOS technology for low power consumption and high-speed asynchronous data transfer
• Provides flexible memory organization suitable for complex buffering and data storage tasks

Applications

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

Procurement Notes

Verify the specific suffix designation carefully during procurement, as variations such as J or G indicate different package types like PLCC or PGA. Confirm RoHS compliance status, as older manufacturing runs may not meet current environmental standards. Check for end-of-life notifications, as this component family has faced discontinuation notices from the manufacturer. Ensure compatibility with existing board layouts regarding the selected package footprint.

Selection Notes

Select this component when dual-port functionality is required for concurrent processor access without arbitration delays. Compare the 25 ns speed grade against system timing requirements to ensure adequate performance margins. Evaluate the 68-PGA package suitability against available PCB space and assembly capabilities. Consider alternative speed grades within the 7133SA series if faster access times are necessary for the target application.

Part Context

This part belongs to the Renesas 7133SA series of dual-port SRAMs, which also includes variants like the 7133LA series offering extended temperature ranges. The series is characterized by its CMOS technology and parallel interface architecture. Previous iterations include parts with different access speeds and package options, reflecting the evolution of memory solutions for high-performance computing needs.

Replacement Considerations

Direct substitutes include the IDT7133SA25G, which shares identical electrical specifications and pinout configurations. Other compatible alternatives within the same family include the 7133SA25J for PLCC packaging or the 7133SA55G for slower access requirements. Verify pin compatibility and electrical parameters before integrating any replacement into the design.
