7143SA20J8

Overview

The Renesas Electronics Corporation 7143SA20J8 is a dual-port static random access memory (SRAM) integrated circuit. It features a storage capacity of 32 kilobits, organized as 2K words by 16 bits. The device supports parallel asynchronous interfaces with a maximum access time of 20 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and is designed for surface-mount installation in a 68-pin PLCC package.

Feature Summary

• Dual-port architecture enabling independent simultaneous access from two separate processors or systems.

Applications

• High-speed data buffering in telecommunications equipment.

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm the specific suffix J8 aligns with required lead-free or packaging specifications. Review official datasheets for updated moisture sensitivity levels and handling instructions prior to integration into manufacturing processes.

Selection Notes

Evaluate the 20ns access speed against system timing requirements. Ensure the 68-PLCC package footprint matches the printed circuit board layout. Verify that the 4.5V to 5.5V operating voltage range is compatible with the target power supply rails and logic levels.

Part Context

This component belongs to the 7143SA series of dual-port SRAMs manufactured by Renesas Electronics. These devices are engineered for applications requiring high-bandwidth memory sharing between multiple masters without bus contention.

Replacement Considerations

Consult official documentation for cross-reference part numbers such as IDT7143SA20J8. Verify pin compatibility and electrical specifications before substituting.
