71342LA55PF8

Overview

The 71342LA55PF8 is a dual-port static random-access memory (SRAM) integrated circuit manufactured by Renesas Electronics Corporation. It provides a storage capacity of 32 kilobits, organized as 4K words by 8 bits. The device features asynchronous parallel interface operation with a maximum access time of 55 nanoseconds. It operates on a single 5V power supply within the voltage range of 4.5V to 5.5V. The component is housed in a 64-lead Thin Quad Flatpack (TQFP) package designed for surface-mount technology applications.

Feature Summary

• Supports simultaneous independent access from two separate ports without internal arbitration logic
• Enables automatic low-power standby mode through chip enable control signals
• Utilizes true dual-ported memory cell architecture for high-speed data transfer

Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing units
• Data logging and temporary storage in industrial automation controllers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability of refurbished units. Confirm RoHS compliance status as this specific variant may not meet current environmental directives. Ensure proper handling procedures are followed during installation to prevent electrostatic discharge damage to the sensitive semiconductor junctions.

Selection Notes

Select this component when designing systems requiring concurrent read/write operations from distinct processors or buses. Evaluate thermal dissipation requirements for the TQFP package under continuous load conditions. Compare performance metrics against alternative SRAM families if lower access times or higher density are required for the specific application constraints.

Part Context

This part belongs to the 71342SA/LA series of dual-port SRAMs. It shares architectural similarities with other members of the family but differs in pinout configuration and packaging style. The LA suffix typically denotes lead-free or specific commercial grade variations compared to the SA series. Understanding the broader series characteristics aids in evaluating compatibility with existing system designs.

Replacement Considerations

Direct replacements include the 71342LA20PFG8, which offers faster 20ns access speed in a similar TQFP-64 package. Verify pin-to-pin compatibility and electrical specifications before substitution. Consider functional equivalents from other manufacturers only after thorough validation of timing parameters and voltage levels.
