7134LA70J8

Overview

The Renesas Electronics Corporation 7134LA70J8 is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits organized as 4K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 70 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Supports independent simultaneous read and write operations on two separate ports for high-throughput data handling.
• Utilizes CMOS technology to provide low power consumption characteristics suitable for battery-operated systems.
• Features TTL-compatible logic levels for straightforward integration with standard digital logic families.

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to obsolete 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 footprint specifications before assembly.

Selection Notes

Select this component when dual-port architecture is required for concurrent processor access. Ensure the design accommodates the 52-PLCC surface mount form factor. Verify that the system voltage remains within the specified 4.5V to 5.5V range to maintain signal integrity and prevent latch-up conditions during operation.

Part Context

This part belongs to the 7134LA series of dual-port SRAMs manufactured by Renesas Electronics. It serves as a legacy solution for applications requiring fast, independent port access without complex arbitration logic. The series provides a robust alternative to single-port memories in multi-master bus architectures.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Engineering teams should consult official manufacturer notices for end-of-life guidance or qualified cross-reference lists.
