71342SA25J

Overview

The Renesas Electronics Corporation 71342SA25J is a dual-port static random access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 4K words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation in a 52-pin 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 construction for low power consumption

Applications

• High-speed data buffering in industrial control systems
• Real-time signal processing applications requiring concurrent access
• Embedded memory solutions for telecommunications equipment

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity and moisture sensitivity handling requirements before assembly. Cross-reference datasheet specifications against current design constraints to ensure compatibility with existing system architectures and voltage levels.

Selection Notes

Evaluate the 25 ns access speed against system timing requirements. Ensure the 52-PLCC package footprint matches the printed circuit board layout. Verify that the 4.5 V to 5.5 V operating voltage aligns with the target power supply rails. Consider the dual-port capability if simultaneous independent access is necessary for the application.

Part Context

This component belongs to the Renesas 71342SA series of dual-port SRAMs. It is manufactured by Renesas Electronics Corporation, formerly part of Integrated Device Technology (IDT).
