7026S35J

Memory IC Overview

The Renesas Electronics Corporation 7026S35J is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 256 kilobits, organized as 16K words by 16 bits. The component features a parallel interface with a maximum access 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 an 84-pin PLCC package. The device is rated for commercial operating temperatures between 0°C and +70°C.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at both Port A and Port B without bus contention
• Provides true dual-port architecture allowing two processors to access the same memory array concurrently
• Features asynchronous operation with simple control logic including chip selects and output enables

Memory IC Applications

• High-performance computing systems requiring shared data buffers
• Telecommunications equipment utilizing message switching architectures
• Industrial automation controllers needing fast local data logging

Memory IC Procurement Notes

Verify current availability status as this component may be discontinued or subject to limited production runs. Confirm RoHS compliance requirements against specific project standards, noting that certain suffixes or manufacturing dates may affect regulatory status. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate pin compatibility with existing PCB footprints before procurement.

Memory IC Selection Notes

Select this component when concurrent bidirectional data transfer is required between two independent system buses. The 35-nanosecond access speed suits moderate-to-high frequency applications. Consider the 84-PLCC package constraints for board space. Evaluate power consumption characteristics against thermal management capabilities in the final enclosure design.

Memory IC Part Context

This part belongs to the IDT/Renesas 7026 series of dual-port SRAMs. It shares architectural similarities with other members like the 7026L15JG but differs in access speed and packaging options. The series is designed for applications demanding high bandwidth and low latency inter-process communication without complex arbitration logic.
