70V05L25PFG

Memory IC Overview

The 70V05L25PFG is an asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It provides a storage capacity of 64 kilobits, organized as 8K words by 8 bits. The device features a parallel interface with a typical access time of 25 nanoseconds. It operates within a supply voltage range of 3.0 volts to 3.6 volts and supports surface-mount installation in a 64-lead Thin Quad Flat Package (TQFP) measuring 14x14 millimeters. The component is designed for industrial temperature ranges spanning from 0°C to 70°C.

Memory IC Feature Summary

• Supports independent simultaneous read and write operations at both Port A and Port B without bus contention
• Provides high-speed data transfer capabilities suitable for demanding real-time processing applications
• Integrates dedicated chip select inputs to facilitate easy expansion and system integration

Memory IC Applications

• High-performance digital signal processing systems requiring low-latency data buffering
• Network communication equipment utilizing packet switching and routing logic

Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm package type and speed grade compatibility. Confirm RoHS compliance status as manufacturing processes may vary across production sites. Ensure the source supplier provides traceability documentation for this discontinued or legacy component series.

Memory IC Selection Notes

Select this component when a dual-port architecture is required to decouple processor and peripheral data paths. Compare the 25-nanosecond access speed against system timing requirements to ensure adequate performance margins. Evaluate the 64-TQFP footprint constraints against available printed circuit board real estate during the layout phase.

Memory IC Part Context

This part belongs to the 70V05L family of asynchronous dual-port SRAMs. It shares architectural similarities with other members like the 70V05L15 and 70V05L35, differing primarily in access speed specifications. The family is characterized by its parallel interface and standard 3.3-volt operation for embedded memory applications.

Memory IC Replacement Considerations

Official upgrade alternatives include the 70V05L15PFG for faster performance or the 70V05L20PFGI8 for tape-and-reel packaging. Verify pinout compatibility before substituting to ensure direct replacement feasibility.
