7025S15PFI

Memory IC Overview

The 7025S15PFI is a dual-port static random access memory integrated circuit manufactured by Renesas Electronics. It provides a storage capacity of 128 kbit organized as 8k x 16 words. The device features an asynchronous parallel interface with a maximum access time of 15 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a maximum power consumption of 320 mA. The component is designed for surface mount installation in a 100-TQFP package, measuring 14x14 mm. It functions reliably across an industrial temperature range from -40°C to +85°C.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes through separate port controllers
• Includes on-chip hardware semaphore signaling for inter-port synchronization
• Features automatic power-down mode controlled by chip enable signals
• Provides TTL-compatible single 5V power supply operation

Memory IC Applications

• High-speed data buffering in communication systems
• Cache memory implementation in embedded processors
• Data logging applications requiring fast write speeds
• Real-time signal processing buffers

Memory IC Procurement Notes

Verify the specific suffix PFI against official Renesas documentation to confirm the exact package type and moisture sensitivity level. Confirm RoHS compliance status as sources indicate non-compliance. Check current lifecycle status as the part may be discontinued or subject to production changes. Ensure the supplier provides valid traceability documents for this legacy component.

Memory IC Selection Notes

Select this component when a true dual-port architecture is required for concurrent data access without external arbitration logic. Consider the 100-TQFP package constraints for PCB layout and thermal management. Evaluate the 15 ns access speed against system timing requirements. Verify that the 5V supply voltage aligns with the target application's power rails.

Memory IC Part Context

This device belongs to the Renesas 7025 series of high-speed dual-port SRAMs. The series offers various access times and packaging options to suit different performance needs. The 7025S15 variant specifically targets applications requiring faster cycle times compared to slower variants in the same family. It serves as a standalone memory solution or can be combined in master/slave configurations for wider data buses.

Memory IC Replacement Considerations

The 7025L20PFGI is listed as a similar replacement option. Verify pin compatibility and electrical specifications before substitution. Note that the L-series may have different temperature ranges or package variations.
