7143LA25PFI8

Overview

The 7143LA25PFI8 is a 32 Kbit (2K x 16) CMOS dual-port static random access memory manufactured by Renesas Electronics. It features asynchronous parallel interface with a maximum access time of 25 ns. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a 100-TQFP package. It is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Dual-port architecture enabling independent simultaneous access
• Asynchronous operation with fast 25 ns access speed
• CMOS technology for low power consumption

Applications

• Embedded systems requiring high-speed data buffering
• Industrial control applications
• Telecommunications equipment

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status as historical records may vary. Check moisture sensitivity level handling requirements before assembly. Ensure supply chain stability due to potential obsolescence risks associated with legacy SRAM families.

Selection Notes

Select this part for designs requiring independent read/write ports on 16-bit data buses. Compare against single-port alternatives if cost reduction is prioritized over concurrency. Verify voltage compatibility with 5V logic systems. Consider pinout differences when replacing older variants like the 7133 series.

Part Context

This component belongs to the 7143LA series of dual-port SRAMs. It shares architectural similarities with the 7133LA series but offers specific packaging and thermal characteristics suited for modern surface-mount technologies. The LA suffix typically denotes extended temperature ratings compared to standard commercial grades.

Replacement Considerations

The 7143LA25PFI8 is listed as obsolete. Potential substitutes include the 7133LA25PFGI8 or other compatible dual-port SRAMs from the same manufacturer family, subject to pin compatibility verification.
