70V05S25PF

Memory IC Overview

The Renesas Electronics Corporation 70V05S25PF is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 64 kbit organized as 8K x 8 bits. The device supports asynchronous parallel interface operation with a maximum access time of 25 ns. It operates within a supply voltage range of 3 V to 3.6 V and has a maximum power supply current of 190 mA. The component is designed for surface mount installation in a 64-pin Thin Quad Flat Package (TQFP) measuring 14x14 mm. It functions reliably across an operating temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations on separate ports
• Asynchronous parallel interface for straightforward integration into standard digital systems
• Single data rate (SDR) memory technology optimized for general-purpose data buffering

Memory IC Applications

• Data buffering in telecommunications equipment
• Cache memory implementation in embedded control systems
• High-speed data acquisition applications requiring low latency

Memory IC Procurement Notes

Verify the exact suffix designation, as official documentation lists 70V05S25PF8. Confirm RoHS compliance status, as specific variants may not meet current environmental regulations. Check manufacturer lifecycle status, as this series is often marked obsolete. Ensure the package type matches the required PCB footprint for the 64-TQFP configuration.

Memory IC Selection Notes

Select this component when a dual-port SRAM with 64 kbit capacity and 25 ns speed is required. Compare against the 70V05L15 variant if faster 15 ns access times are necessary. Verify that the 3.3 V logic levels align with the system's I/O requirements. Consider the PLCC-68 alternative if through-hole mounting is preferred over surface mount.

Memory IC Part Context

This part belongs to the Renesas 70V05S family of dual-port SRAMs. These devices are engineered for high-performance data handling in industrial and commercial applications. The family provides flexible memory solutions with varying speeds and package options to suit different design constraints and performance needs.

Memory IC Replacement Considerations

The 70V05S25PF8 is the verified direct substitute with identical electrical specifications. The 70V05L15PFG offers a faster 15 ns access time but requires verification of pin compatibility.
