71342SA25JI

Overview

The Renesas Electronics Corporation 71342SA25JI is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 4096 words by 8 bits. The device features an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 52-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports.

Applications

• High-speed data buffering in industrial equipment.

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations exist between J8 and JI packages. Confirm RoHS compliance status, as specific variants may not meet current environmental standards. Check for end-of-life notifications or obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when a system requires independent concurrent access to shared memory via two distinct address and data buses. Ensure the design accommodates the 52-PLCC footprint and meets the 4.5V to 5.5V power supply requirements for reliable operation.

Part Context

This part belongs to the 7134SA series of dual-port SRAMs manufactured by Renesas Electronics. These devices are designed for applications requiring high-speed data transfer between different processing domains without bus contention.

Replacement Considerations

Consult official substitution lists for verified equivalents. Generic cross-references should be validated against pinout and electrical specifications.
