7027L25PFI

Memory IC Overview

The Renesas Electronics Corporation 7027L25PFI is a dual-port static random-access memory (SRAM) device organized as 32K words by 16 bits, providing a total storage capacity of 512 kbit. It operates with asynchronous parallel interfaces and features a maximum access time of 25 ns. The component supports a supply voltage range from 4.5 V to 5.5 V and functions within an operating temperature range of -40°C to +85°C. It is housed in a 100-lead Thin Quad Flat Package (TQFP) with a 14x14 mm footprint, designed for surface-mount installation.

Memory IC Feature Summary

• Dual-port architecture enabling independent read/write operations on two separate ports simultaneously
• Asynchronous operation allowing flexible timing control without external clock synchronization
• Parallel interface supporting standard data bus widths for direct microprocessor connection

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in industrial control systems
• Data storage in embedded network processing units

Memory IC Procurement Notes

Verify RoHS compliance status as the component may not meet current environmental directives. Confirm package integrity upon receipt, as lead frames can be susceptible to bending during handling. Ensure voltage levels match system requirements strictly within the 4.5V to 5.5V range to prevent damage. Check for obsolescence notices or lifecycle changes that may affect long-term availability.

Memory IC Selection Notes

Select this part when dual-port functionality is required for simultaneous host and peripheral access. Compare access times against system clock speeds to ensure 25 ns meets latency requirements. Verify thermal management capabilities for the -40°C to +85°C industrial range. Consider pin compatibility if replacing legacy IDT variants in existing designs.

Memory IC Part Context

This component belongs to the 7027L series of high-performance dual-port SRAMs. It shares architectural similarities with other members like the 7027L55PFI but offers faster 25 ns access compared to slower variants. The series is designed for applications requiring independent port access without complex arbitration logic.

Memory IC Replacement Considerations

IDT7027L25PFI serves as a direct functional equivalent due to shared naming conventions and specifications.
