7134LA35P

Overview

The Renesas Electronics Corporation 7134LA35P is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 32 kbit organized as 4K x 8. It features parallel interface access and supports a supply voltage range from 4.5 V to 5.5 V. The component offers a maximum access time of 35 ns and operates within an industrial temperature range of -55°C to +125°C. It utilizes a 48-pin LCC surface-mount package and includes automatic power-down capabilities controlled by chip enable signals.

Feature Summary

• True dual-ported memory cells allow simultaneous independent access to the same memory location from either port without on-chip hardware arbitration.
• Fully asynchronous operation enables flexible timing control for systems that cannot tolerate wait states or require external contention handling.
• Automatic power-down feature permits low standby power consumption when controlled by the chip enable signal.

Applications

• Systems requiring simultaneous data access from two independent processors or controllers.
• High-speed buffer applications where zero wait-state operation is critical.
• Industrial equipment operating in extreme temperature environments.
• Battery-backed memory systems utilizing the LA series 2V data retention capability.

Procurement Notes

Verify the specific suffix against official documentation, as the provided model number may differ from standard commercial listings. Confirm RoHS compliance status and lead-free availability directly with the manufacturer or authorized distributors. Check for end-of-life notices or obsolescence warnings prior to procurement. Ensure the 48-pin LCC package matches the target PCB footprint requirements. Validate the industrial temperature grade suitability for the intended operational environment.

Selection Notes

Select this component for designs requiring true dual-port functionality with asynchronous timing flexibility. Consider the 35 ns access speed relative to system clock requirements. Evaluate the 4.5 V to 5.5 V supply voltage compatibility with existing logic levels. Assess the need for industrial temperature range (-55°C to +125°C) versus commercial grades. Verify package constraints for the 48-pin LCC form factor during layout planning.

Part Context

The 7134LA series belongs to Renesas' high-speed dual-port SRAM family, designed for applications needing concurrent access without internal arbitration. These parts are often used in telecommunications and industrial control systems. The 'LA' designation typically indicates extended temperature ranges and battery backup support. This series complements other asynchronous memory solutions by providing dedicated dual-port architecture for complex data sharing tasks.

Replacement Considerations

Publicly confirmed substitute part numbers for the exact 7134LA35P specification were not identified in the available source material. Cross-reference with IDT7134LA35 variants if historical naming conventions apply. Verify pinout and electrical parameter compatibility before substituting any similar dual-port SRAM components.
