7025S15PFG

Memory IC Overview

The 7025S15PFG is a high-speed, asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It features a storage capacity of 128 kilobits organized as 8K words by 16 bits. The device supports simultaneous independent access from two separate ports, enabling concurrent read and write operations without bus contention. It operates with a single 5V power supply and offers an access time of 15 nanoseconds. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with a 14x14 mm footprint.

Memory IC Feature Summary

• True dual-port architecture allowing simultaneous independent access to the same memory location from both ports
• Integrated hardware support for semaphore signaling and on-chip port arbitration logic
• Separate upper-byte and lower-byte control lines designed for multiplexed bus compatibility
• Automatic power-down feature controlled by Chip Enable signals for low standby power consumption

Memory IC Applications

• High-performance data buffering in telecommunications systems
• Cache memory implementation in embedded processing architectures
• Data logging applications requiring non-volatile backup capabilities
• Multiprocessor systems utilizing master/slave dual-port configurations

Memory IC Procurement Notes

Verify the specific suffix designation against official Renesas documentation to confirm temperature range and package variations. Confirm RoHS compliance status as historical records indicate potential discrepancies for older manufacturing lots. Check current production lifecycle status, as this part number may be subject to obsolescence notices or replacement recommendations. Ensure ordering quantities align with standard manufacturer packaging constraints.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data transfer is required between two independent processors or buses. The 15ns access speed suits applications demanding rapid data exchange. Consider the 100-pin TQFP package for surface-mount assembly requirements. Evaluate system voltage stability to ensure consistent operation within the specified 5V tolerance limits during peak load conditions.

Memory IC Part Context

This device belongs to the Renesas 7025 series of dual-port SRAMs, which are widely utilized in industrial and commercial electronics. The series provides scalable memory solutions for complex digital signal processing tasks. The 7025 family is known for its robust interrupt flag functionality and battery backup retention capabilities, supporting data integrity during power transitions.

Memory IC Replacement Considerations

Official substitutes include the 7025L15PFGI for industrial temperature range applications and the 7025S20PFGI for slightly slower access times. Verify pinout compatibility and electrical specifications before substitution. Consult Renesas Product Change Notices for any functional updates or end-of-life directives affecting this series.
