7134SA45CB

Overview

The Renesas Electronics Corporation 7134SA45CB is a static random access memory (SRAM) component with a storage capacity of 32Kb, organized as 4K x 8. It features dual-port asynchronous operation and parallel interface connectivity. The device has a maximum access time of 45 ns and operates within a supply voltage range of 4.5V to 5.5V. It is housed in a CDIP-SB-48 package and supports an operating temperature range of 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling simultaneous independent access by two masters
• Asynchronous parallel interface for flexible system integration
• High-speed data transfer capabilities suitable for real-time applications

Applications

• Industrial equipment requiring high-speed data buffering
• Communication systems utilizing dual-master data exchange
• Embedded control systems needing fast volatile memory

Procurement Notes

Verify the discontinuation status through official manufacturer channels before procurement planning. Confirm RoHS compliance requirements against specific project standards, as this part may not meet current environmental directives. Ensure that the CDIP-SB-48 package type matches existing PCB footprints and assembly processes. Check for any available last-time buy notifications or end-of-life notices from Renesas Electronics to manage supply chain risks effectively.

Selection Notes

Select this component when dual-port functionality is required for concurrent master access without bus contention. The 45 ns access speed suits applications demanding rapid data retrieval. Verify that the 4.5V to 5.5V supply voltage aligns with the target system's power rails. Consider the through-hole CDIP-SB-48 package if surface-mount options are unsuitable for the mechanical design.

Part Context

This SRAM belongs to the 7134SA series, designed for high-performance embedded applications. It provides reliable volatile memory storage with dual-port independence. The component integrates standard parallel interfaces for straightforward connection to microprocessors and controllers in industrial and communication environments.

Replacement Considerations

Check for direct pin-compatible replacements within the same series. Verify electrical parameters such as access time and voltage ranges match exactly. Consult manufacturer documentation for approved substitute part numbers.
