7134SA20J8

Overview

The Renesas 7134SA20J8 is a dual-port static random access memory (SRAM) device organized as 4K words by 8 bits. It features asynchronous parallel interface operation with a maximum access time of 20 nanoseconds and write cycle time of 20 nanoseconds. The component operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. It is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface mount technology. The device supports an operating temperature range from 0°C to +70°C.

Feature Summary

• True dual-port architecture enabling simultaneous independent access to the same memory location from both ports without hardware arbitration.
• Fully asynchronous operation allowing flexible timing control for systems requiring external arbitration or contention handling.
• Automatic power-down feature controlled by chip enable signals to reduce standby power consumption.

Applications

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

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm package integrity and moisture sensitivity level handling requirements before assembly. Check for specific RoHS compliance variations across manufacturing dates. Ensure replacement parts match pinout and electrical specifications exactly.

Selection Notes

Select this component for designs requiring true dual-port memory capabilities with fast asynchronous access. Consider the PLCC52 package constraints for PCB layout. Evaluate power consumption profiles against system requirements. Verify compatibility with existing logic levels and timing constraints.

Part Context

This part belongs to the Renesas 7134 series of dual-port SRAMs, previously manufactured under IDT branding. It represents a legacy high-speed memory solution designed for applications needing concurrent read/write operations from two distinct masters.

Replacement Considerations

IDT7134SA20J8 is a confirmed equivalent part number representing the same component prior to corporate rebranding.
