7134SA25JI

Overview

The Renesas Electronics Corporation 7134SA25JI is a high-speed, 32-kbit Dual-Port Static Random Access Memory (SRAM) organized as 4K words by 8 bits. It features fully asynchronous operation with a maximum access time of 25 nanoseconds, allowing simultaneous independent access to the same memory location from either port without hardware arbitration. The device operates on a single TTL-compatible 5V power supply within a voltage range of 4.5V to 5.5V. It is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount installation.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to shared locations
• Fully asynchronous operation eliminating wait states for flexible system integration
• Automatic power-down feature controlled by chip enable inputs for low standby current
• TTL-compatible logic levels simplifying interface design with standard digital components

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control and automation networks
• Real-time signal processing applications requiring low latency

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability of refurbished units. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Review official datasheets for specific electrical characteristics and pin configurations to ensure compatibility with existing circuit designs.

Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. Consider the 52-pin PLCC package constraints for PCB layout and thermal management. Evaluate the 25ns access speed against system timing requirements and verify that the 5V operating voltage aligns with the target platform's power distribution network.

Part Context

This part belongs to the Renesas 7134 series of dual-port SRAMs, which are designed for applications demanding high-speed concurrent read/write operations. The series offers various speed grades and package options to suit different performance and form factor requirements in embedded and industrial environments.

Replacement Considerations

Official cross-reference documentation indicates IDT7134SA25JI as a compatible substitute part number. Verify pinout compatibility and electrical specifications before substitution.
