7134SA45J

Overview

The Renesas Electronics Corporation 7134SA45J 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 an asynchronous parallel interface with a maximum access time of 45 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 and write operations on separate ports.

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Real-time data logging in industrial control units

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and lead condition upon receipt. Check for RoHS compliance discrepancies as the part may not meet current environmental standards. Validate datasheet revisions against specific manufacturing lot requirements before integration into final designs.

Selection Notes

Select this component when dual-port functionality is required for concurrent bus access. Ensure system voltage aligns with the specified 4.5V to 5.5V operating range. Consider the 52-PLCC footprint constraints during PCB layout. Evaluate thermal performance within the commercial temperature range if ambient conditions exceed standard limits.

Part Context

This SRAM belongs to the IDT 7134 series, designed for high-performance asynchronous memory applications. The series offers various speed grades and packaging options to suit different system requirements. The 7134SA45J specifically targets cost-sensitive designs requiring moderate speed and dual-port capabilities.

Replacement Considerations

Consult official documentation for direct pin-compatible substitutes within the same family. Verify electrical parameters and timing characteristics match original specifications. Cross-reference with manufacturer obsolescence notices for recommended upgrade paths.
