7134LA20JI8

Overview

The Renesas Electronics Corporation 7134LA20JI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a total 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 20 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for straightforward integration into standard digital systems
• CMOS technology construction ensuring low power consumption during operation

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network communication devices

Procurement Notes

Verify component authenticity through authorized channels due to potential availability from legacy production cycles. Confirm RoHS compliance status, as older variants may not meet current environmental directives. Validate package integrity upon receipt, as PLCC components require careful handling to prevent lead damage during installation.

Selection Notes

Select this component when dual-port functionality is required for concurrent data access without bus contention. Ensure the design accommodates the 52-PLCC footprint and 4.5V to 5.5V power requirements. Consider the 20ns access speed against system timing constraints to guarantee reliable data retrieval.

Part Context

This part belongs to the IDT 7134LA series of high-performance dual-port SRAMs manufactured by Renesas Electronics. The series offers various speed grades and package options to suit different performance and form-factor needs in embedded memory applications.

Replacement Considerations

Direct substitutes include other parts within the 7134LA family with compatible pinouts and electrical characteristics. Verify that any replacement maintains the 32Kb capacity and 20ns access speed specifications.
