7026S15J

Memory IC Overview

The Renesas Electronics Corporation 7026S15J is a high-speed, 256K-bit (16K x 16) Dual-Port Static Random Access Memory. It features an asynchronous parallel interface with a maximum access time of 15 nanoseconds. The device operates on a single 5.0V supply voltage within the range of 4.5V to 5.5V. It is housed in an 84-pin Plastic Leadless Chip Carrier package designed for surface-mount installation. The component supports independent read and write operations on both ports simultaneously.

Memory IC Feature Summary

• Dual-port architecture enabling simultaneous independent access by two processors
• Automatic power-down mode controlled by chip enable inputs
• TTL-compatible I/O levels for direct system integration

Memory IC Applications

• Stand-alone dual-port memory systems
• Master/Slave dual-port RAM configurations for 32-bit or larger word systems
• High-speed data buffering between asynchronous logic blocks

Memory IC Procurement Notes

Verify current availability status as this component may be discontinued. Confirm RoHS compliance requirements against specific project standards. Ensure proper handling procedures are followed due to moisture sensitivity classification. Validate pinout compatibility during design-in phase to prevent hardware errors.

Memory IC Selection Notes

Select this part when simultaneous bidirectional data transfer is required without bus contention. Compare access speeds against other variants in the 7026 series to match system timing constraints. Verify package dimensions fit the target PCB layout constraints before finalizing the bill of materials.
