7005S35PF8

Overview

The Renesas Electronics Corporation 7005S35PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 64 kilobits. The device features an 8K x 8 organization and utilizes a parallel interface for data transfer. It operates within a supply voltage range of 4.5V to 5.5V and supports a maximum access time of 35 nanoseconds. The component is housed in a 64-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm and is designed for surface-mount installation. It functions reliably across an industrial temperature range from 0°C to +70°C.

Feature Summary

• Supports simultaneous independent reads and writes from two distinct ports without bus contention
• Includes on-chip hardware logic for semaphore signaling and port arbitration between master and slave configurations
• Provides automatic power-down functionality controlled by chip enable signals to minimize standby current consumption

Applications

• High-speed data buffering in telecommunications equipment
• Cache memory implementation in embedded processing systems
• Data logging applications requiring concurrent host and peripheral access

Procurement Notes

Verify the specific suffix PF8 confirms the tape-and-reel packaging format and lead-free status if required by assembly processes. Confirm that the RoHS compliance status aligns with environmental regulations for the target deployment region. Ensure the operating temperature range meets the thermal requirements of the final system enclosure. Validate pin compatibility against existing PCB footprints before initiating procurement actions.

Selection Notes

Select this component when a design requires true dual-port memory architecture for concurrent data handling. The 35ns access speed suits moderate-to-high frequency asynchronous interfaces. Consider the 64-TQFP package constraints regarding board space and thermal dissipation. Evaluate the need for internal arbitration logic versus external management solutions for multi-master environments.

Part Context

This part belongs to the 7005 series of dual-port SRAMs manufactured by Renesas Electronics. The series is engineered for applications demanding independent port access and hardware-based synchronization. The 7005S35 variant specifically denotes the 35ns speed grade within the standard voltage family. It serves as a foundational memory solution for legacy and specialized industrial control architectures.
