7134LA55J

Overview

The Renesas Electronics Corporation 7134LA55J is a static random access memory (SRAM) device featuring dual-port asynchronous architecture. It provides a storage capacity of 32 kbit, organized as 4K words by 8 bits. The component supports parallel interface communication with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 52-PLCC surface-mount package. The device is designed for commercial temperature environments ranging from 0°C to +70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation without requiring a system clock signal
• CMOS technology ensuring low power consumption relative to older bipolar alternatives

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• FIFO buffer applications in industrial control networks

Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance. Confirm end-of-life or obsolescence status through official manufacturer channels before finalizing design integration. Ensure supply chain stability due to potential discontinuation risks associated with legacy memory components.

Selection Notes

Select this component when dual-port independence is required for concurrent read/write operations. Compare against single-port variants if simultaneous access is unnecessary. Verify package compatibility with existing PCB footprints, specifically the 52-PLCC form factor. Consider thermal management requirements within the specified commercial temperature range.

Part Context

This part belongs to the Renesas 7134SA/LA series of dual-port SRAMs. It shares architectural similarities with other members like the 7134SA55J but may differ in specific electrical characteristics or packaging options. The series is characterized by high-speed asynchronous access suitable for complex digital logic interfacing.

Replacement Considerations

Official substitute part numbers include IDT7134LA55J. Verify pinout and electrical parameter equivalence before substitution. Cross-reference datasheets to ensure functional compatibility regarding access times and voltage levels.
