7134LA35J8

Overview

The Renesas Electronics Corporation 7134LA35J8 is a high-speed, 32-kbit (4K x 8) dual-port static random-access memory. It features fully asynchronous parallel operation from either port and supports simultaneous access to the same memory location without on-chip hardware arbitration. The device operates within a voltage range of 4.5V to 5.5V and includes an automatic power-down feature controlled by chip enable signals for low standby power. It is housed in a 68-pin LCC (J-Lead) surface-mount package.

Feature Summary

• True dual-ported memory cells enabling simultaneous independent access to shared locations
• Fully asynchronous operation eliminating wait states for both ports
• Automatic power-down mode controlled by chip enable inputs for reduced standby consumption

Applications

• Systems requiring external arbitration for concurrent data access
• High-speed buffer applications tolerant of contention
• Parallel interface memory subsystems

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm package integrity and moisture sensitivity handling requirements prior to assembly. Review official discontinuation notices for lifecycle status updates. Ensure compatibility with existing system voltage levels and timing specifications before integration.

Selection Notes

Select this component for designs necessitating true dual-port capability with asynchronous control. Suitable for architectures where external logic manages port contention rather than internal arbitration. Verify that the 68-pin LCC package aligns with board layout constraints and thermal management strategies.

Part Context

This part belongs to the 7134 series of dual-port SRAMs originally developed by Integrated Device Technology (IDT). Following corporate acquisitions, the product line is now managed under Renesas Electronics. The series provides high-speed volatile memory solutions for specialized parallel processing environments.

Replacement Considerations

Consult official documentation for qualified substitute part numbers. Cross-reference pinouts and electrical characteristics carefully when evaluating alternatives.
