7132LA25J8

Overview

The Renesas Electronics Corporation 7132LA25J8 is a dual-port static random-access memory (SRAM) device. It features a storage capacity of 32 kbit, organized as 4K words by 8 bits. The component supports asynchronous parallel interface operations with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 52-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.

Applications

• High-speed data buffering between asynchronous logic blocks.
• Cache memory implementation in embedded processing systems.
• Data storage for telecommunications equipment requiring fast read/write cycles.

Procurement Notes

Verify the specific suffix J8 against official Renesas documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status through current manufacturer notices, as older PLCC variants may differ. Check for active production status or obsolescence notices prior to design finalization.

Selection Notes

Select this component when dual-port functionality is required for shared memory access without external arbitration logic. Ensure the system voltage aligns with the 4.5 V to 5.5 V operating range. Verify that the 25 ns access speed meets the timing requirements of the target application bus.

Part Context

This part belongs to the Renesas 7132 series of high-performance SRAMs. It is designed for applications requiring reliable, fast data storage with independent port control. The PLCC-52 package provides a robust surface-mount solution for industrial and commercial environments.

Replacement Considerations

Consult official Renesas cross-reference guides for verified substitutes. Generic equivalents may lack identical dual-port timing characteristics or pin compatibility.
