7025L15PF8

Memory IC Overview

The Renesas Electronics Corporation 7025L15PF8 is a high-speed, asynchronous dual-port static random-access memory (SRAM) device. It provides a storage capacity of 128 kbit, organized as 8K words by 16 bits per word. The component features a parallel interface with an access time of 15 ns. It operates on a single 5V power supply, with voltage specifications ranging from a minimum of 4.5 V to a maximum of 5.5 V. The device supports surface-mount installation in a 100-pin TQFP package and functions within an industrial temperature range of 0°C to +70°C.

Memory IC Feature Summary

• True dual-ported architecture enabling simultaneous independent read and write operations from two separate ports without conflict.
• Integrated hardware semaphore signaling logic for automatic port arbitration and data integrity management.
• Supports multiplexed bus compatibility through separate upper-byte and lower-byte control signals.
• Includes interrupt flag capabilities and automatic power-down modes controlled by chip enable inputs.

Memory IC Applications

• Stand-alone 128K-bit dual-port RAM systems
• Master/Slave dual-port configurations for expanded 32-bit or wider data bus architectures
• High-speed data buffering in telecommunications equipment
• Network switch and router internal memory structures

Memory IC Procurement Notes

Verify the specific suffix 'PF8' against official Renesas documentation to confirm pinout and package dimensions, as suffixes define physical characteristics. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for active obsolescence notices or production discontinuation alerts directly from the manufacturer before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a system requires true dual-port memory with hardware-managed arbitration rather than software-controlled sharing. It is suitable for applications needing fast, asynchronous access to shared data buffers. Ensure the design accommodates the 100-pin TQFP footprint and the specified 5V logic levels. Consider thermal dissipation limits if operating near the upper temperature boundary.

Memory IC Part Context

The 7025 series represents a family of high-performance dual-port SRAMs designed for complex embedded systems. This specific model belongs to the 7025L variant line, which typically denotes standard commercial or industrial temperature ranges compared to military-grade counterparts. The series is widely utilized in networking and industrial automation where reliable, concurrent memory access is critical for system performance.

Memory IC Replacement Considerations

The 7025S35PF8 is documented as an obsolete upgrade path within the same product family. Verify electrical compatibility and pin alignment before substitution. No other direct cross-references are confirmed in available public records.
