7026L55J

Memory IC Overview

The Renesas Electronics Corporation 7026L55J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 256 kilobits, organized as 16K words by 16 bits. The device features asynchronous parallel interface technology with a maximum access time of 55 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-pin Plastic Leadless Chip Carrier (PLCC) package measuring 29.31x29.31 mm. The component is rated for commercial operating temperatures between 0°C and 70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous read/write operations from two separate ports.

Memory IC Applications

• High-speed data buffering in telecommunications systems
• Cache memory implementation in embedded processing units
• Data storage in industrial control networks

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Validate package integrity upon receipt, ensuring no pin damage occurred during handling or shipping. Cross-reference datasheet revisions to ensure compatibility with existing design specifications.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent data access. Ensure system power supplies remain stable within the 4.5V to 5.5V range. Verify that the 84-PLCC footprint matches the printed circuit board layout. Consider thermal management capabilities within the specified commercial temperature range.

Memory IC Part Context

This SRAM belongs to the 7026 series, designed for high-performance memory applications. It complements other variants like the 7026L35J and 7026S25J, which offer faster access times but may differ in packaging or speed grades. The series utilizes advanced CMOS technology for reliable operation in standard digital logic environments.

Memory IC Replacement Considerations

Official substitutes include the 7026L35J and 7026S25J. These alternatives provide identical memory organization but feature reduced access times of 35 ns and 25 ns respectively. Verify pin compatibility and electrical characteristics before integration.
