7025L55PFI

Memory IC Overview

The Renesas Electronics Corporation 7025L55PFI is a dual-port static random-access memory (SRAM) device with a storage capacity of 128 kbit, organized as 8K x 16. It features an asynchronous parallel interface with a maximum access time of 55 ns. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in a TQFP-100 package. It is designed for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

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

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid write cycles

Memory IC Procurement Notes

Verify RoHS compliance status as the specific suffix PFI may indicate lead-free or restricted substance variations compared to older IDT versions. Confirm current lifecycle status as many 7025 series parts are discontinued. Check humidity sensitivity levels for proper handling during assembly. Ensure pin compatibility with existing PCB footprints before ordering.

Memory IC Selection Notes

Select this part when dual-port functionality is required for shared memory access between multiple masters. Compare access times against system timing constraints to ensure 55 ns meets latency requirements. Verify package dimensions fit within mechanical enclosure limits. Consider thermal dissipation capabilities for high-density board layouts.

Memory IC Part Context

This component belongs to the 7025 series of dual-port SRAMs originally developed by Integrated Device Technology (IDT) and later acquired by Renesas Electronics. The series offers various speed grades and package options to support diverse embedded memory needs in industrial and commercial applications.

Memory IC Replacement Considerations

Check for direct pin-compatible replacements such as the 7025L55S55G or other 7025 series variants with matching electrical specifications. Verify that any substitute maintains the same 8Kx16 organization and 55 ns access time.
