7143LA55J8

Overview

The Renesas Electronics Corporation 7143LA55J8 is a dual-port static random access memory (SRAM) IC with a storage capacity of 32 kbit, organized as 2K x 16. It features an asynchronous parallel interface and a maximum access time of 55 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation in a 68-PLCC package. It is designed for commercial temperature ranges from 0°C to 70°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous operation with fast 55 ns access time
• CMOS technology for low power consumption

Applications

• High-speed data buffering in communication systems
• Cache memory applications in embedded processors
• FIFO buffers in digital signal processing

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for moisture sensitivity level handling instructions during storage and assembly. Validate pin compatibility if replacing existing designs.

Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. Ensure system voltage aligns with the 4.5V to 5.5V operating range. Consider the 68-PLCC package constraints for PCB layout. Evaluate thermal performance within the commercial temperature limits.

Part Context

This SRAM belongs to the 7143SA/LA series, which provides high-speed dual-port memory solutions. The 'LA' suffix typically denotes extended temperature or specific packaging variations compared to the 'SA' series. It serves as a volatile memory solution for applications requiring rapid data exchange between multiple bus masters.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify cross-references with IDT7143LA55J8 or similar variants only if officially documented by the manufacturer.
