70V05S25PFI

Memory IC Overview

The Renesas Electronics Corporation 70V05S25PFI is a static random access memory (SRAM) device belonging to the 70V05S series. It features a storage capacity of 64 kbit organized as 8K x 8 bits. The component operates with an asynchronous parallel interface and provides a maximum access time of 25 ns. It supports a supply voltage range from 3 V to 3.6 V. The device is housed in a 64-LQFP surface-mount package and is rated for operation within a temperature range of 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access
• Asynchronous operation from either port without clock synchronization
• On-chip hardware support for semaphore signaling between ports

Memory IC Applications

• High-speed data buffering in embedded systems
• Cache memory implementation in microprocessor designs
• Data logging applications requiring fast write cycles

Memory IC Procurement Notes

Verify RoHS compliance status carefully, as documentation indicates non-compliance for this specific part number. Confirm moisture sensitivity level requirements during handling. Check for obsolescence notices or last-time buy notifications due to potential discontinuation. Ensure supplier sources provide original manufacturer packaging to prevent counterfeit risks.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations. Compare against single-port alternatives if only one processor accesses the memory. Consider the 64-TQFP package constraints for PCB layout. Evaluate power consumption specifications against system thermal limits.

Memory IC Part Context

This SRAM belongs to the Renesas 70V05S family of high-speed dual-port memories. The family typically offers various access speeds and organization options. These devices are designed for applications requiring full hardware support for inter-port communication and arbitration logic.
