7132LA25JI8

Overview

The Renesas Electronics Corporation 7132LA25JI8 is a dual-port static random access memory (SRAM) integrated circuit. It features a storage capacity of 16 kilobits, organized as 2K words by 8 bits. The device supports parallel interface communication with an access time of 20 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and is housed in a TQFP-64 surface-mount package. The component is designed for asynchronous operation and includes internal master write control capabilities.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct controllers
• Integrated internal master write control mechanism for simplified data management
• Asynchronous parallel interface supporting standard logic levels

Applications

• Data buffering in high-speed digital signal processing systems
• Cache memory implementation in embedded microcontroller architectures
• Temporary storage in telecommunications equipment interfaces

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations may indicate different temperature ranges or packaging options. Confirm current production status, as this specific part number may be subject to discontinuation notices. Ensure compatibility with existing board layouts regarding the TQFP-64 footprint and pin configuration before procurement.

Selection Notes

Select this component when a system requires independent read/write ports for concurrent data handling without external arbitration logic. The 20-nanosecond access speed suits moderate-to-high frequency applications. Verify that the 4.5V to 5.5V operating voltage aligns with the target system's power rails. Consider the TQFP-64 package constraints for thermal management and PCB space availability.

Part Context

This device belongs to the Renesas 71321 series of dual-port SRAMs. It shares architectural similarities with other members like the 71321LA20PFG8 but differs in access speed and specific control features. The series is characterized by CMOS technology and parallel interface standards, targeting industrial and commercial applications requiring reliable volatile memory solutions.

Replacement Considerations

Cross-reference with IDT71321LA20PFG8 for functional similarity, noting differences in access time. Verify pinout compatibility and electrical specifications before substitution. Consult official Renesas obsolescence notices for authorized replacement recommendations.
