7134SA25J

Overview

The Renesas Electronics Corporation 7134SA25J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 4K words by 8 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 52-pin PLCC package. The component is designed for commercial temperature ranges from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation without requiring a system clock signal
• CMOS technology providing low power consumption characteristics

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• FIFO buffer applications in industrial control networks

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as this variant may not meet current environmental directives. Validate package integrity upon receipt to ensure pin alignment matches the 52-PLCC specification before soldering.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave operations. Ensure the design accommodates the 52-PLCC footprint and 4.5V to 5.5V power rails. Consider thermal management for the commercial grade operating range if ambient temperatures approach the upper limit of 70°C during continuous high-frequency access cycles.

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 speed grade and packaging. The '25' suffix indicates the 25 nanosecond access time classification, distinguishing it from slower or faster alternatives within the same product line.

Replacement Considerations
