7132LA25JI

Overview

The Renesas Electronics Corporation 7132LA25JI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits organized as 2K by 8 bits. The device operates with an access time of 25 nanoseconds and supports parallel interface communication. It functions within a supply voltage range of 4.5 volts to 5.5 volts. The component is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package, specifically identified as 52-PLCC with dimensions of 19.13mm by 19.13mm. It is designed for surface mount installation and supports asynchronous operation modes.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems
• Asynchronous operation allowing flexible timing control without requiring a global clock signal
• CMOS technology providing low power consumption characteristics relative to older memory technologies

Applications

• Data buffering between high-speed processors and slower peripheral devices
• Cache memory implementation in embedded computing systems
• Temporary data storage in telecommunications equipment interfaces

Procurement Notes

Verify the exact suffix configuration against official Renesas documentation, as variations such as J8 or C may indicate different packaging or temperature grades. Confirm RoHS compliance status directly with the manufacturer, as historical batches often lack modern environmental certifications. Check for active End-of-Life notices or discontinuance announcements prior to finalizing procurement plans to ensure long-term supply stability.

Selection Notes

Select this component when a design requires independent read/write ports for concurrent data handling without bus contention. Ensure the system voltage aligns with the specified 4.5V to 5.5V operating range. Verify that the PCB footprint accommodates the 52-PLCC package dimensions. Consider the 25ns access speed against system timing requirements to guarantee reliable data transfer rates during peak operations.

Part Context

This part belongs to the Renesas 7132 series of dual-port SRAMs, which are widely used in applications requiring high-speed data exchange between multiple masters. The LA variant typically denotes specific performance or packaging characteristics within the broader product family. These components serve as critical intermediaries in complex digital systems where data integrity and low-latency access are paramount for overall system performance.

Replacement Considerations

IDT7132LA25JI is a confirmed equivalent part number under the Integrated Device Technology brand, now part of Renesas.
