7134SA55JG

Overview

The 7134SA55JG is a 32Kb dual-port static random access memory (SRAM) manufactured by Renesas Electronics Corporation. It features an asynchronous parallel interface with a memory organization of 4K x 8 bits. The device supports a supply voltage range of 4.5V to 5.5V and offers a maximum access time of 55 ns. It is housed in a 52-PLCC surface-mount package and operates within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on both ports
• Asynchronous parallel interface for straightforward integration into standard logic systems
• CMOS technology providing low power consumption characteristics relative to older bipolar alternatives

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 component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements as specific batches may vary. Check for moisture sensitivity level handling instructions during assembly. Validate pin compatibility with existing PCB footprints before procurement.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. Ensure the system operates within the specified 4.5V to 5.5V voltage window. Consider the 55 ns access speed against application latency requirements. Verify that the PLCC-52 package fits the available board space constraints.

Part Context

This part belongs to the Renesas 7134SA series of dual-port SRAMs. It shares architectural similarities with other variants in the family but differs in package type and speed grade. The 7134SA series is designed for applications requiring high-speed, non-volatile-like behavior without the complexity of flash programming cycles.

Replacement Considerations

The 71342LA20JG is listed as a similar replacement option by the manufacturer.
