7025L17PFI

Memory IC Overview

The Renesas Electronics Corporation 7025L17PFI is an asynchronous dual-port static random-access memory (SRAM) device. It features a storage capacity of 128 kbit, organized as 8K words by 16 bits. The component supports parallel interface communication with a maximum access time of 17 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 100-pin Thin Quad Flat Package (TQFP). The device is designed for surface-mount installation and functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array via two distinct port sets.

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 current availability status as this component may be subject to discontinuation or limited stock constraints. Confirm RoHS compliance requirements against specific project standards, noting that older variants often lack full environmental certification. Validate pin compatibility and thermal characteristics during integration planning to ensure reliable operation under specified load conditions.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master-slave operations without bus contention. Ensure the design accommodates the 100-pin TQFP footprint and meets the 4.5V to 5.5V power supply specifications. Consider the 17 ns access speed relative to system clock frequencies to prevent timing violations in high-performance asynchronous interfaces.

Memory IC Part Context

This part belongs to the Renesas 7025 series of dual-port SRAMs, which are widely utilized in networking and industrial control applications. The series offers various access speeds and package options to suit different performance and form-factor requirements. As a legacy component, it represents established CMOS technology for non-volatile-free high-speed memory solutions.

Memory IC Replacement Considerations

Direct substitutes include the IDT7025L17PFI and other variants within the 7025L family sharing identical pinouts and electrical characteristics. Verify functional equivalence regarding access times and voltage ranges before substitution.
