7132LA35JI

Overview

The Renesas Electronics Corporation 7132LA35JI 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 with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V. The component is housed in a 52-PLCC package with dimensions of 19.13x19.13 mm. It supports surface mount installation and functions within an operating temperature range of -40°C to 85°C.

Feature Summary

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

Applications

• High-speed data buffering in telecommunications equipment requiring concurrent read/write operations.
• Cache memory subsystems in embedded processing architectures needing rapid data retrieval.
• Network switch fabric buffers for packet storage and forwarding in industrial networking hardware.

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical and mechanical specifications. Confirm RoHS compliance status as it varies by manufacturing date and region. Check for product discontinuation notices or end-of-life announcements prior to finalizing procurement plans. Ensure compatibility with existing board layouts regarding the 52-PLCC footprint and pin configuration.

Selection Notes

Select this component when dual-port functionality is required for shared memory access between multiple masters. Consider the 35ns speed grade if system timing constraints demand faster access than lower-grade variants offer. Evaluate the 52-PLCC package suitability for automated surface-mount assembly processes. Compare thermal performance requirements against the specified operating temperature range for the target application environment.

Part Context

This part belongs to the IDT 7132 series of dual-port SRAMs originally developed by Integrated Device Technology and later acquired by Renesas Electronics. The series is designed for applications requiring high-performance memory sharing. The 7132LA variant specifically denotes the commercial/industrial temperature range options available within the broader product family.

Replacement Considerations

Consult official Renesas datasheets for verified cross-reference part numbers. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution. Check for updated packaging options or lead-free alternatives that may have replaced the original specification.
