7026S15J8

Memory IC Overview

The Renesas Electronics Corporation 7026S15J8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) IC. It provides a storage capacity of 256 kilobits organized as 16K words by 16 bits. The device features parallel interface access with a maximum access time of 15 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and supports surface-mount installation in an 84-pin PLCC package measuring 29.31x29.31 mm. The component functions reliably across a commercial temperature range of 0°C to 70°C.

Memory IC Feature Summary

• Supports simultaneous independent read/write operations from two separate ports for concurrent data processing
• Provides high-speed asynchronous parallel data transfer capabilities
• Designed for standalone dual-port RAM applications or integration into larger memory systems

Memory IC Applications

• High-performance computing systems requiring concurrent memory access
• Telecommunications equipment utilizing dual-port buffering
• Industrial control systems needing fast data exchange between processors

Memory IC Procurement Notes

Verify the specific suffix J8 confirms the 84-PLCC package configuration and lead type. Confirm RoHS compliance status as documentation may vary by production date. Check for obsolescence notices or end-of-life declarations from Renesas. Ensure the supplier provides valid traceability documents for this discontinued component series.

Memory IC Selection Notes

Select this component when dual-port architecture is required for simultaneous host and peripheral access. Compare access times against system clock requirements to ensure 15ns performance meets timing constraints. Verify voltage compatibility with the 4.5V to 5.5V operating range. Consider the 84-PLCC footprint for PCB layout compatibility during design phase.
