7134SA55J8

Overview

The Renesas Electronics Corporation 7134SA55J8 is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 4K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 52-pin PLCC package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.
• Asynchronous operation allowing flexible timing control without reliance on a global clock signal.
• CMOS technology implementation for efficient power consumption relative to performance requirements.

Applications

• High-speed data buffering between microprocessors and peripheral devices.
• Cache memory implementation in embedded computing systems.
• Data storage in telecommunications equipment requiring rapid read/write cycles.

Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance requirements against specific project regulations, as this variant may not meet current environmental standards. Validate package integrity upon receipt to ensure pin alignment matches the 52-PLCC specification before soldering.

Selection Notes

Select this component when dual-port functionality is required for concurrent system access. Ensure the design accommodates the 55 ns access speed and 5V logic levels. Consider the 52-PLCC footprint constraints during PCB layout. Evaluate alternative packages if higher density or different interface speeds are needed for future scalability.

Part Context

This part belongs to the Renesas 7134SA series of dual-port SRAMs. It shares architectural similarities with other variants in the family but differs in organization and packaging. The J8 suffix typically denotes specific tape-and-reel packaging configurations distinct from tube-packaged equivalents like the JG variant.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs if considering cross-brand alternatives, noting potential differences in pinout and electrical characteristics.
