7026S25JI8

Memory IC Overview

The Renesas Electronics Corporation 7026S25JI8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) with a storage capacity of 256 kbit. The memory organization is structured as 16K x 16 bits, providing independent access to the same memory location from two separate ports. It features a parallel interface and operates within a supply voltage range of 4.5 V to 5.5 V. The component has an access time of 25 ns and is designed for surface-mount installation in an 84-pin PLCC package. It supports an industrial operating temperature range from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access to shared memory locations
• Asynchronous operation allowing flexible timing control from either port
• Automatic power-down mode controlled by chip enable signals for low standby power

Memory IC Applications

• Stand-alone dual-port RAM systems
• Master/Slave dual-port configurations for 32-bit or wider word systems
• High-speed data buffering in embedded applications

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as indicated specifications may vary. Check moisture sensitivity level handling procedures before assembly. Validate pinout compatibility with existing PCB layouts. Review official datasheets for latest electrical characteristics and thermal limits.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. Ensure system voltage aligns with the 4.5V to 5.5V operational range. Consider the 84-PLCC package constraints for board space. Verify that the 25ns access time meets system timing requirements. Evaluate thermal management needs for the specified temperature range.
