7134SA55P

Memory IC Overview

The 7134SA55P is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 32 kilobits, organized as 4K words by 8 bits. The device utilizes an asynchronous parallel interface with a maximum access time and write cycle time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports through-hole mounting in a 48-pin plastic dual in-line package (PDIP). The component is designed for commercial temperature applications ranging from 0°C to 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access by two processors
• Asynchronous operation without requiring a system clock signal
• CMOS technology ensuring low power consumption during read and write cycles

Memory IC Applications

• High-speed data buffering between microprocessors and peripherals
• Cache memory implementation in embedded systems
• Data storage in industrial control units

Memory IC Procurement Notes

Verify the specific suffix 'P' corresponds to the 48-PDIP package configuration. Confirm RoHS compliance status as older variants may not meet current environmental directives. Check for obsolescence notices or end-of-life declarations from the manufacturer before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a dual-port memory solution is required for asynchronous parallel communication. Ensure the design accommodates the 48-pin DIP footprint and the 4.5V to 5.5V power supply requirements. Consider thermal management within the specified commercial operating temperature range.

Memory IC Part Context

This part belongs to the 7134SA family of dual-port SRAMs. Variants in this series differ primarily in access speed, memory organization, and package type. The 7134SA55P specifically denotes the 55ns speed grade and PDIP packaging within the broader product line.

Memory IC Replacement Considerations

Consult official manufacturer documentation for verified cross-references. Alternative packages such as PLCC or TQFP may exist within the same functional family but require physical redesign.
