7132LA35PDG

Overview

The 7132LA35PDG is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. 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 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount or through-hole installation in a 48-pin dual in-line package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors
• Asynchronous parallel interface for straightforward integration into existing logic systems
• CMOS technology ensuring low power consumption during read and write operations

Applications

• High-speed data buffering between microprocessors and peripheral devices
• Cache memory implementation in embedded control systems
• Data logging applications requiring rapid sequential write access

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as older batches may differ. Check moisture sensitivity level handling procedures before soldering. Validate pin compatibility with target PCB footprint. Review datasheet revisions for any functional updates prior to final design approval.

Selection Notes

Select this component when dual-processor communication requires non-blocking memory access. Ensure the system voltage aligns with the 4.5V to 5.5V operating range. Consider the 35ns access speed relative to processor clock cycles. Evaluate the 48-DIP package constraints against available board space and assembly methods compared to alternative packages like PLCC or TQFP.

Part Context

This part belongs to the 7132LA series of dual-port SRAMs. It shares architectural similarities with other members like the 7132LA35J8, differing primarily in package type and manufacturing origin history. The series is designed for applications needing high-speed, independent port access without complex arbitration logic.
