7132LA55J8

Overview

The Renesas Electronics Corporation 7132LA55J8 is a high-speed static random access memory (SRAM) device featuring dual-port asynchronous architecture. It provides a storage capacity of 16 kbit, organized as 2k x 8 bits per port. The component supports parallel interface operations with an access time of 55 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 52-PLCC package. The device is designed for surface-mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Dual-port asynchronous architecture enabling independent simultaneous access by two masters
• High-speed parallel data transfer capabilities for efficient system integration
• Industrial-grade operational stability across extended temperature ranges

Applications

• Data buffering in telecommunications equipment
• Cache memory implementation in embedded systems
• FIFO buffer applications in industrial control networks

Procurement Notes

Verify component authenticity through authorized distributors due to obsolete status. Confirm RoHS compliance requirements against specific project standards. Validate package integrity upon receipt. Check datasheet revisions for any pinout or electrical characteristic updates prior to final design approval.

Selection Notes

Select this component when dual-port functionality is required for concurrent master access. Ensure the 55 ns speed meets system timing constraints. Verify that the 52-PLCC footprint aligns with existing PCB layout specifications. Consider power consumption limits relative to the 5V supply environment.

Part Context

This part belongs to the Renesas 71321/7133 series of dual-port SRAMs. It shares architectural similarities with other members like the 71321SA55JI8 but differs in package type and specific revision codes. The 'LA' suffix typically denotes lead-free and environmental compliance variations within the product family.

Replacement Considerations

Direct substitutes include IDT7132LA55J8. Verify pin compatibility and electrical parameters before substitution.
