7026S25J

Memory IC Overview

The Renesas Electronics Corporation 7026S25J is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 256 kbit, organized as 16K words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 25 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports surface-mount installation in an 84-pin PLCC package. The component is designed for commercial temperature environments ranging from 0°C to +70°C.

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access to the same memory array
• Asynchronous operation without requiring external clock synchronization
• Parallel data interface supporting standard logic levels

Memory IC Applications

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

Memory IC Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance requirements against specific project standards, as indicated by non-compliant markings in some records. Validate package integrity upon receipt, noting moisture sensitivity classification. Ensure design-in compatibility with existing system voltage and timing constraints before procurement.

Memory IC Selection Notes

Select this component when dual-port functionality is required for concurrent master access. Compare access speeds against alternative models if higher throughput is necessary. Verify package footprint compatibility with printed circuit board layouts. Consider obsolescence management strategies given the discontinued manufacturing status.

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 differs in speed grade and packaging options. The 'J' suffix typically denotes specific package or environmental variants within the product line.

Memory IC Replacement Considerations

Direct substitutes are not explicitly confirmed in available public documentation. Evaluate newer Renesas dual-port SRAM families for functional equivalence. Verify pinout compatibility and electrical parameter alignment before considering alternative part numbers.
