71342SA55PFI

Memory IC Overview

The Renesas Electronics Corporation 71342SA55PFI is a high-speed, 32Kbit (4K x 8) dual-port static RAM featuring asynchronous parallel interface technology. It operates within a voltage range of 4.5V to 5.5V and supports an access time of 55ns. The component is housed in a 64-pin Thin Quad Flat Pack (TQFP) with dimensions of 14x14mm, designed for surface-mount installation. It functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

Provides fully independent semaphore logic blocks to assist in arbitrating memory access between the two ports.
Features true dual-ported memory cells allowing simultaneous access to the same memory location from either port.
Includes an automatic power-down mechanism controlled by chip enable and semaphore signals for low standby power.

Memory IC Applications

High-speed data buffering in telecommunications equipment
Real-time processing systems requiring concurrent read/write operations
Industrial control units needing reliable dual-port memory arbitration

Memory IC Procurement Notes

Verify component authenticity through authorized channels as this part is discontinued. Confirm package integrity and pin alignment against the 64-TQFP specification. Check datasheet revisions for any label changes or substitution notices issued by Renesas. Ensure compatibility with existing circuit designs regarding voltage levels and timing requirements before integration.

Memory IC Selection Notes

Select this component when asynchronous dual-port SRAM functionality is required with specific semaphore support for port arbitration. Consider the 64-TQFP package constraints and industrial temperature rating (-40°C to +85°C). Evaluate if the 55ns access time meets system performance needs compared to faster alternatives like the 25ns variant.

Memory IC Part Context

This device belongs to the 71342SA/LA series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family but is distinguished by its specific 55ns speed grade and TQFP packaging. The series is known for integrating hardware semaphore logic directly on-chip to manage multi-port access conflicts efficiently.
