7025L25PFI8

Memory IC Overview

The Renesas Electronics Corporation 7025L25PFI8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 128 kilobits organized as 8K words by 16 bits. The component features a parallel interface with a maximum access time of 25 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The device is housed in a 100-pin Thin Quad Flat Package (TQFP) designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent read and write operations at both Port A and Port B without bus contention
• Includes on-chip hardware semaphore logic for automatic port arbitration and interrupt flag signaling
• Features separate upper-byte and lower-byte control lines to enable multiplexed bus compatibility

Memory IC Applications

• Stand-alone 128K-bit dual-port memory systems
• Master/Slave dual-port RAM configurations for 32-bit or wider data word systems
• High-speed data buffering between asynchronous processing units

Memory IC Procurement Notes

Verify the specific suffix PFI8 against official Renesas documentation to confirm package dimensions and lead finish specifications. Confirm that the RoHS status aligns with current environmental compliance requirements for your assembly process. Check for any Product Change Notifications regarding labeling or material updates before finalizing procurement orders.

Memory IC Selection Notes

Select this component when simultaneous bidirectional data access is required without external arbitration logic. The 25ns speed grade offers a balance between performance and power consumption compared to faster variants. Ensure the design accommodates the 100-pin TQFP footprint and thermal dissipation characteristics associated with this package type.

Memory IC Part Context

This part belongs to the Renesas 7025 family of dual-port SRAMs, which are designed for applications requiring true dual-ported memory cells. The family supports various access times and packaging options to suit different system timing and physical layout constraints while maintaining compatible functional interfaces.

Memory IC Replacement Considerations

Consult official Renesas documentation for verified cross-reference part numbers. Verify pinout compatibility and electrical parameter alignment before substituting.
