7134LA35JI

Overview

The Renesas Electronics Corporation 7134LA35JI is a high-speed, dual-port static random-access memory (SRAM) integrated circuit. It features an 8Kb storage capacity organized as 1K x 8 bits with parallel interface access. The device operates asynchronously with a maximum access time of 35 ns and supports a single 5V power supply within the 4.5V to 5.5V range. It is housed in a 52-pin PLCC surface-mount package and is designed for applications requiring simultaneous independent access from two ports without on-chip arbitration.

Feature Summary

• Supports true dual-ported memory cells allowing simultaneous access to the same memory location from both ports
• Features fully asynchronous operation suitable for systems capable of external port arbitration or contention handling
• Includes automatic power-down functionality controlled by chip enable signals to minimize standby power consumption

Applications

• Systems requiring simultaneous data exchange between two independent processors
• Buffering applications where wait states are not tolerated
• Hardware designs utilizing external arbitration mechanisms for shared memory access

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures prior to assembly. Review official datasheets for specific electrical characteristics and operating conditions relevant to your design requirements.

Selection Notes

Select this component when dual-port architecture is required for concurrent read/write operations. Ensure system design includes external arbitration logic to manage potential bus contention during simultaneous accesses. Verify voltage compatibility with the specified 5V supply range and confirm thermal performance meets operational temperature specifications.

Part Context

This part belongs to the IDT/Renesas 7134 series of dual-port SRAMs. These devices are engineered for high-performance embedded systems needing fast, non-blocking memory access. The series typically offers various speed grades and packaging options to accommodate different board space and timing constraints in industrial and commercial applications.

Replacement Considerations

Consult manufacturer documentation for officially confirmed substitute part numbers. Verify pinout compatibility and electrical parameter alignment before substitution.
