7143SA25JI8

Overview

The Renesas Electronics Corporation 7143SA25JI8 is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 25 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in a 68-pin Plastic Leadless Chip Carrier (PLCC) package.

Feature Summary

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

Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data logging in industrial control equipment

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and moisture sensitivity handling requirements before assembly. Cross-reference datasheet revisions for any pinout or electrical specification updates prior to final design integration.

Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Ensure the system voltage aligns with the specified 4.5V to 5.5V range. Consider the 68-PLCC package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the 7143SA series of high-performance dual-port SRAMs manufactured by Renesas Electronics. The series is designed for applications requiring fast, independent access to shared memory resources without bus contention.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative dual-port SRAMs based on pinout and electrical specifications.
