70261L35PF8

Memory IC Overview

The 70261L35PF8 is a dual-port static random-access memory (SRAM) manufactured by Renesas Electronics. It provides a storage capacity of 256 kbit, organized as 16k words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 35 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 100-pin TQFP package. The component supports surface-mount installation and is designed for industrial temperature ranges.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems
• Asynchronous parallel interface supporting standard logic levels for flexible integration
• High-density 256 kbit storage capacity optimized for data buffering and cache applications

Memory IC Applications

• Data buffering between high-speed processors and slower peripheral devices
• Cache memory implementation in embedded control systems
• Network equipment packet storage and switching buffers
• Industrial automation controller memory modules

Memory IC Procurement Notes

Verify the exact suffix configuration against the manufacturer datasheet to ensure compatibility with specific voltage and packaging requirements. Confirm RoHS compliance status as older batches may differ. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans. Ensure moisture sensitivity level handling procedures are followed during assembly.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent read/write operations without bus contention. Compare access times and power consumption against single-port alternatives if only one processor is used. Verify that the 100-TQFP package fits the available PCB footprint and thermal constraints. Consider lifetime availability given the component's age.

Memory IC Part Context

This part belongs to the Renesas 70261 series of dual-port SRAMs. It shares architectural similarities with other members like the 70261L20 and 70261S35 variants, differing primarily in speed grade and temperature rating. The series is designed for applications requiring high-speed data sharing between independent systems.
