7026S55J8

Memory IC Overview

The Renesas Electronics Corporation 7026S55J8 is a dual-port static random-access memory (SRAM) integrated circuit. It features a storage capacity of 256 kilobits, organized as 16K words by 16 bits. The device utilizes an asynchronous parallel interface with a maximum access time of 55 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in an 84-lead Plastic Leadless Chip Carrier (PLCC) package, measuring 29.31mm by 29.31mm. It supports surface mount installation and functions within a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent access to the same memory location from two separate ports
• Provides full hardware support for semaphore signaling between ports
• Includes on-chip port arbitration logic with busy and interrupt flags

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 applications requiring concurrent read/write operations

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity upon receipt, as moisture sensitivity level 3 requires proper handling. Ensure design compatibility with 5V logic levels and PLCC footprint dimensions before finalizing procurement plans.

Memory IC Selection Notes

Select this component when concurrent dual-port access is required for high-speed data processing. Verify that the 55ns access time meets system timing requirements. Ensure the design accommodates the 84-PLCC package constraints and commercial temperature operating limits.

Memory IC Part Context

This part belongs to the 7026S series of dual-port SRAMs manufactured by Renesas Electronics. It shares architectural similarities with other members of the family but is distinguished by its specific 256Kb density and 55ns speed grade. The series is designed for applications demanding high-performance memory with independent port control.
