7025S35PFI

Memory IC Overview

The 7025S35PFI is a high-speed, asynchronous dual-port static random-access memory (SRAM) manufactured by Renesas Electronics Corporation. It provides a storage capacity of 128 kilobits organized as 8K words by 16 bits. The device features a parallel interface with a maximum access time and write cycle time of 35 nanoseconds. It operates on a single 5V power supply within a voltage range of 4.5V to 5.5V. The component is housed in a 100-pin Thin Quad Flat Package (TQFP) with dimensions of 14x14 mm, designed for surface-mount installation.

Memory IC Feature Summary

• Supports simultaneous independent reads and writes from either port without conflict
• Includes on-chip hardware semaphore signaling for port arbitration
• Features automatic power-down mode controlled by chip enable signals
• Provides interrupt flag generation and status monitoring capabilities

Memory IC Applications

• Stand-alone 128K-bit dual-port memory systems
• Master/Slave configurations for 32-bit or wider data bus expansion
• High-speed data buffering between asynchronous logic blocks
• Real-time signal processing applications requiring concurrent access

Memory IC Procurement Notes

Verify the specific suffix requirements against current Renesas documentation, as package and temperature variants exist. Confirm RoHS compliance status, as older revisions may not meet current environmental standards. Check for active obsolescence notices or production discontinuation alerts before finalizing procurement plans. Ensure the selected variant matches the required operating temperature range for the target application environment.

Memory IC Selection Notes

Select this component when concurrent independent access to shared memory is required without external arbitration logic. Choose the TQFP package for surface-mount assembly constraints. Verify that the 35ns speed meets the system timing requirements. Consider the 5V supply compatibility with existing TTL-level interfaces. Evaluate the need for industrial temperature ranges if operating conditions exceed commercial limits.

Memory IC Part Context

This part belongs to the 7025 series of dual-port SRAMs, which are designed for high-performance data sharing between two processors or logic systems. The series offers various speed grades and package options to suit different design constraints. These devices are commonly used in telecommunications, networking equipment, and industrial control systems where data integrity and low-latency access are critical.

Memory IC Replacement Considerations

Check for direct pin-compatible upgrades such as the 7025L series if lower power consumption is needed. Verify that substitute parts maintain the same 8Kx16 organization and 35ns access time. Ensure replacement packages match the 100-TQFP footprint. Confirm that any new part supports the same semaphore and interrupt functionality.
