7143LA25PFI

Overview

The Renesas Electronics Corporation 7143LA25PFI is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 32 kbit, organized as 2k x 16 bits. The device features an asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power supply current of 300 mA. The component is housed in a 100-pin TQFP package with dimensions of 14x14 mm. It is designed for surface-mount installation and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access by two masters
• Asynchronous operation without requiring a system clock signal
• CMOS technology ensuring low power consumption during standby

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in network infrastructure hardware

Procurement Notes

Verify the specific suffix PFI confirms the 100-TQFP package and commercial/industrial temperature grade. Confirm RoHS compliance status through official documentation, as legacy variants may differ. Check for moisture sensitivity level requirements if the component has been stored for extended periods. Ensure the ordering quantity aligns with manufacturer minimum order quantities for tape-and-reel packaging. Validate that the source document matches the exact part number to avoid confusion with similar series members.

Selection Notes

Select this component when a dual-port SRAM with 25 ns access speed is required for 16-bit wide data paths. It is suitable for applications needing independent read/write ports without bus contention. Consider the 100-pin TQFP footprint for PCB layout constraints. Verify that the 4.5 V to 5.5 V supply voltage matches the system design. Evaluate thermal management needs given the 300 mA maximum current draw at peak operation.

Part Context

This part belongs to the Renesas 7143LA series of dual-port SRAMs. It shares architectural similarities with other devices in the family but differs in pin count and package type. The 7143LA series is designed for high-performance memory applications requiring fast asynchronous access. It serves as a bridge between high-speed processors and slower peripheral devices in complex electronic systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with IDT7143LA25PFI only if explicitly stated as equivalent in official datasheets. Verify pin compatibility and electrical specifications before substitution.
