7132LA70JI

Overview

The Renesas Electronics Corporation 7132LA70JI is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 70 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-pin PLCC package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for flexible system integration
• CMOS technology ensuring low power consumption during operation

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data storage in industrial control applications

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements against project specifications, as this variant may not meet current environmental standards. Validate package integrity upon receipt to ensure pin alignment matches the 52-PLCC footprint. Review datasheet revisions for any functional updates prior to final design approval.

Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave or peer-to-peer data exchange. Ensure the 70ns access speed meets system timing constraints. Verify that the 52-PLCC package fits the available PCB real estate. Consider thermal management capabilities within the specified operating temperature range during layout planning.

Part Context

This part belongs to the Renesas 7132 series of dual-port SRAMs. It shares architectural similarities with other variants in the family but differs in speed grade and packaging. The 70ns speed class positions it for moderate-speed asynchronous applications compared to faster counterparts.

Replacement Considerations

Check for direct pin-compatible substitutes within the same series. Verify electrical parameter equivalence for access time and voltage ranges before substitution.
