70V05S35PF8

Memory IC Overview

The 70V05S35PF8 is an obsolete asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage capacity of 64 kilobits organized as 8K words by 8 bits. The device utilizes a parallel interface with a maximum access time and write cycle time of 35 nanoseconds. It operates within a supply voltage range of 4.5 volts to 5.5 volts and supports surface-mount installation in a 100-pin TQFP package with dimensions of 14x14 millimeters. The component is designed for industrial temperature ranges from 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two separate ports without bus contention.
• Features fully asynchronous operation allowing flexible timing control from either port.
• Includes on-chip hardware support for semaphore signaling to facilitate data synchronization between ports.

Memory IC Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring rapid sequential access

Memory IC Procurement Notes

This specific part number is officially discontinued and no longer in production. Verification of availability should focus exclusively on the designated upgrade path, specifically the 70V05L15PFG model. Procurement must account for the end-of-life status, ensuring that any acquired units are sourced from authorized distributors or verified surplus channels to guarantee authenticity and proper handling history.

Memory IC Selection Notes

Designers seeking this component should evaluate the recommended replacement, 70V05L15PFG, which offers enhanced performance characteristics. Selection criteria must prioritize compatibility with existing board layouts and pin configurations. Engineers should verify that the upgraded model meets all system requirements regarding voltage levels, speed, and package dimensions before finalizing the bill of materials.
