7133LA25PFI

Memory IC Overview

The Renesas Electronics Corporation 7133LA25PFI is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 32 kbit organized as 2K x 16 bits. The device supports asynchronous parallel interface with an access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum power supply current of 300 mA. The component is housed in a 100-pin TQFP package suitable for surface mount technology. It functions within a commercial temperature range of 0°C to +70°C.

Memory IC Feature Summary

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

Memory IC Applications

• High-performance embedded systems requiring fast data buffering
• Network equipment cache memory applications
• Industrial control systems needing reliable volatile storage

Memory IC Procurement Notes

Verify the specific suffix PFI against your bill of materials, as it denotes a tray package variant distinct from reel-packaged versions like PFGI8. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for obsolescence notices or lifecycle changes directly from Renesas, as availability may vary significantly between distributors. Ensure the 100-TQFP footprint matches your PCB design constraints.

Memory IC Selection Notes

Select this component when a 32 Kbit dual-port SRAM with 25 ns access speed is required in a 100-lead TQFP package. Compare against the 7133SA series if industrial temperature ranges (-40°C to +85°C) are necessary instead of the commercial range. Consider the 7133LA25PFGI8 if tape-and-reel packaging is preferred for automated assembly over tray handling.

Memory IC Part Context

This part belongs to the Renesas 7133LA series of dual-port SRAMs. It shares architectural similarities with the IDT7133LA family but carries Renesas branding following corporate acquisitions. The 'LA' designation typically indicates commercial temperature grade and specific pinout compatibility within the broader 7133 product line.

Memory IC Replacement Considerations

The 7133LA25PFGI8 serves as a direct functional substitute with identical electrical specifications, differing only in packaging format (reel vs. tray). For industrial temperature requirements, the 7133SA25PFI offers equivalent performance across a wider thermal range.
