7026S25JI

Memory IC Overview

The Renesas Electronics Corporation 7026S25JI is a high-speed, asynchronous dual-port static random access memory (SRAM) device. It provides a storage capacity of 256 kbit organized as 16K words by 16 bits. The component features a parallel interface with an access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface mount installation in an 84-pin PLCC package. The device is designed for independent read/write operations on both ports.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations through two separate ports
• Includes automatic power-down functionality controlled by chip enable signals
• Utilizes TTL-compatible I/O levels for standard logic interfacing

Memory IC Applications

• Stand-alone dual-port RAM configurations
• Master/Slave dual-port RAM combinations for 32-bit or larger word systems
• High-performance data buffering applications requiring concurrent port access

Memory IC Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations such as J, JG, or JGI may indicate differences in packaging, lead finish, or environmental compliance status. Confirm current availability status directly with authorized distributors, as this component series has been subject to discontinuation notices. Ensure that the specific part number matches the required package type and operating temperature range before procurement.

Memory IC Selection Notes

Select this component when a system requires true dual-port memory architecture allowing concurrent access without arbitration overhead. The 25 ns access speed suits moderate-to-high frequency digital signal processing tasks. Verify that the 84-PLCC package fits the target PCB layout constraints. Consider alternative members of the 7026 family if different access times or industrial temperature ranges are required for the specific application environment.

Memory IC Part Context

The 7026S25JI belongs to the Renesas 7026 series of high-speed dual-port SRAMs. This series is engineered for applications demanding high bandwidth and low latency between two independent processors or bus masters. The device represents a legacy solution for parallel memory interfaces, often found in established industrial and telecommunications equipment designs requiring reliable, synchronous-like data handling via asynchronous control.
