71V424L12PHG

Overview

The 71V424L12PHG is a 4Mb (512K x 8) asynchronous static random-access memory IC manufactured by Renesas Electronics Corporation. It features a parallel interface with a maximum access time of 12 ns. The device operates on a single 3V to 3.6V power supply and supports surface-mount installation in a 44-TSOP II package, which measures 0.400 inches (10.16 mm) in width. It is designed for commercial temperature ranges from 0°C to 70°C.

Feature Summary

• Asynchronous parallel SRAM architecture providing independent read and write operations without external clock synchronization.
• High-speed data access capability optimized for real-time processing applications requiring low latency.
• Single voltage supply operation simplifies power distribution design within standard 3.3V logic systems.

Applications

• Buffering data in high-performance computing systems
• Cache memory implementation in embedded controllers
• Data storage in industrial automation equipment

Procurement Notes

Verify component authenticity through authorized channels due to potential availability of refurbished units. Confirm RoHS compliance status matches specific manufacturing lot requirements. Check for lead-free solder finish specifications to ensure compatibility with assembly processes. Validate package dimensions against PCB footprint designs prior to procurement.

Selection Notes

Select this component when a 4Mb capacity with 12 ns speed is required in a 44-pin TSOP form factor. Ensure the application environment remains within the specified commercial temperature range. Verify that the system power supply strictly adheres to the 3V to 3.6V operating limits to prevent functional instability or damage.

Part Context

This part belongs to the 71V424 series of asynchronous SRAMs, offering various speed grades and package options. The 'L' suffix typically denotes lower power consumption characteristics compared to standard variants. The PHG suffix identifies the specific 44-TSOP II package configuration used for surface-mount technology integration.

Replacement Considerations

Direct replacements include other 71V424 series parts with compatible pinouts and electrical parameters. Verify speed grade equivalence if timing constraints are critical. Consider package compatibility when substituting with different suffix variants within the same family.
