71342LA25J

Overview

The Renesas Electronics Corporation 71342LA25J is an asynchronous dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits, organized as 4096 words by 8 bits. The device supports parallel interface operations with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and is housed in a 52-lead Plastic Leadless Chip Carrier (PLCC) package designed for surface-mount technology.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Parallel data bus interface supporting standard high-speed digital communication protocols

Applications

• Data buffering between microprocessors and peripheral devices
• Cache memory implementation in embedded computing systems
• High-speed data logging applications requiring rapid write and read cycles

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as older batches may not meet current environmental standards. Check moisture sensitivity level handling requirements during assembly. Ensure the specific suffix matches the required package type and temperature grade for your design.

Selection Notes

Select this component when dual independent access is required for shared memory resources. Compare access times against system clock speeds to ensure timing compatibility. Evaluate power consumption limits against available thermal management solutions. Consider package availability and pin compatibility with existing PCB footprints.

Part Context

This part belongs to the Renesas 71342 series of dual-port SRAMs. These components are designed for applications requiring high-speed data sharing between two masters. The series offers various speed grades and package options to suit different performance and space constraints in industrial and commercial electronics.

Replacement Considerations

Check for direct pin-compatible upgrades within the same manufacturer family. Verify that substitute parts maintain identical voltage levels and access times. Ensure alternative packages fit the existing board layout without modification.
