7143LA20PF8

Overview

The Renesas Electronics Corporation 7143LA20PF8 is a high-speed, asynchronous dual-port static random access memory (SRAM) with a density of 32 kbit. The device features a memory organization of 2K words by 16 bits and supports parallel interface communication. It operates within a supply voltage range of 4.5 V to 5.5 V and provides an access time of 20 ns. The component is designed for surface-mount installation in a 68-pin PLCC package.

Feature Summary

• True dual-ported memory architecture enabling simultaneous independent access from two ports.
• On-chip port arbitration logic manages bus conflicts without external discrete components.
• TTL-compatible single 5V power supply operation simplifies system integration.

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data storage in industrial control applications

Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different temperature ranges or packaging options. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the selected variant matches the required lead frame material and pin configuration for the target PCB footprint.

Selection Notes

Select this component when a system requires concurrent read/write operations from separate processors or buses. Evaluate the 20 ns access speed against system clock requirements. Consider the 68-pin PLCC package constraints for board space and thermal management during the design phase.

Part Context

This part belongs to the 7143 series of dual-port SRAMs manufactured by Renesas Electronics. The series utilizes CMOS technology to provide high-speed performance with low power consumption. These devices are commonly used in applications requiring shared memory resources between multiple masters.

Replacement Considerations

IDT7143LA20JG8 is a confirmed substitute offering identical specifications and pinout compatibility.
