71342SA55J

Overview

The Renesas Electronics Corporation 71342SA55J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 4K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-lead Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for flexible system integration
• CMOS technology ensuring low power consumption during operation

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data storage in industrial control equipment

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure packaging specifications match assembly line capabilities. Validate end-of-life status and long-term supply continuity before finalizing orders.

Selection Notes

Select this component when dual-port functionality is required for concurrent data handling. Consider the 55ns access speed against system timing requirements. Evaluate the 52-PLCC package dimensions for PCB layout compatibility. Assess operating temperature range suitability for the intended environment.

Part Context

This part belongs to the Renesas 71342 series of dual-port SRAMs. It shares architectural similarities with other members like the 71342LA20 and 7134SA55 variants, differing primarily in speed grade and package type. The series is designed for applications requiring high-bandwidth memory access between two independent masters.

Replacement Considerations

Check for pin-compatible alternatives such as the IDT71342SA55JG if available. Verify electrical parameter equivalence for access time and voltage ranges. Confirm package footprint compatibility to avoid PCB redesign.
