71342SA20PF8

Overview

The Renesas Electronics Corporation 71342SA20PF8 is a high-speed, 32-kbit (4K x 8) dual-port static random-access memory. It features fully asynchronous parallel operation with a 20 ns access time and operates on a single 5V power supply ranging from 4.5V to 5.5V. The device utilizes a 64-pin TQFP surface-mount package and supports an industrial operating temperature range of -40°C to +85°C. Maximum supply current is specified at 240 mA.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access to the same memory location from both ports without contention.

Applications

• High-speed data buffering in communication systems requiring full-speed error-free operation
• Network equipment acting as shared memory between multiple processors
• Industrial control systems requiring robust dual-port data exchange

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as older variants may not meet current environmental standards. Validate moisture sensitivity level handling procedures during assembly. Ensure replacement parts match the specific suffix codes for package and temperature grade requirements.

Selection Notes

Select this component when true dual-port functionality is required for simultaneous read/write operations. Consider the 64-TQFP package for surface-mount applications. Verify that the 5V logic compatibility meets system voltage levels. Check if the industrial temperature range satisfies environmental constraints compared to commercial grades.

Part Context

This part belongs to the IDT 71342 series of dual-port SRAMs, designed for systems needing hardware-independent port arbitration. It serves as a successor to earlier generations like the 71342SA25PFI8, offering faster 20 ns access times while maintaining the same 32Kb density and 64-pin form factor.
