71342SA25J8

Overview

The 71342SA25J8 is a dual-port static random access memory (SRAM) integrated circuit manufactured by Renesas Electronics. It provides a total storage capacity of 32 kilobits, organized as 4K words by 8 bits. The device features asynchronous parallel interfaces for both ports, allowing independent read and write operations. Key electrical specifications include an access time of 25 nanoseconds and a write cycle time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 52-pin Plastic Leadless Chip Carrier (PLCC) package with dimensions of 19.13x19.13 mm.

Feature Summary

• Supports simultaneous independent read and write operations through two distinct ports
• Utilizes asynchronous parallel interface architecture for flexible data transfer
• Provides volatile memory storage suitable for high-speed temporary data buffering

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications requiring fast access times

Procurement Notes

This component has reached the end-of-life stage and is officially discontinued by the manufacturer. Availability is restricted to existing stock or third-party distributors. Verify authenticity carefully due to potential obsolescence risks. Confirm package integrity and moisture sensitivity level handling requirements before integration into production workflows.

Selection Notes

Select this part when a dual-port SRAM with 32Kb capacity and 25ns speed is required. Ensure the design accommodates the 4.5V to 5.5V supply voltage range. The 52-PLCC package must be supported by the PCB layout. Consider that the device is obsolete and plan for long-term supply constraints or alternative sourcing strategies.

Part Context

The 71342SA25J8 belongs to the 71342SA series of dual-port SRAMs from Renesas Electronics. It shares architectural similarities with other members like the 71342LA25J8 but differs in specific operational characteristics. This series is designed for applications needing concurrent port access without complex arbitration logic, distinguishing it from single-port memory devices.
