7025L45PF8

Memory IC Overview

The Renesas Electronics Corporation 7025L45PF8 is an asynchronous dual-port static random-access memory (SRAM) component. It features a storage capacity of 128 kbit, organized as 8K words by 16 bits per word. The device supports parallel interface communication with a maximum access time of 45 ns. It operates within a supply voltage range of 4.5 V to 5.5 V and is housed in a 100-pin Thin Quad Flat Package (TQFP). This component is designed for applications requiring independent simultaneous access from two distinct ports.

Memory IC Feature Summary

• Supports true dual-ported architecture allowing simultaneous independent reads and writes from separate ports
• Includes on-chip hardware support for semaphore signaling and port arbitration logic
• Features interrupt flag capabilities and automatic power-down modes controlled by chip enable signals

Memory IC Applications

• High-speed data buffering in multiprocessor systems
• Cache memory implementation in embedded controllers
• Data logging and temporary storage in industrial automation equipment

Memory IC Procurement Notes

Verify the specific suffix PF8 against official Renesas documentation to confirm package type and tape-and-reel configuration. Ensure compatibility with existing PCB footprints for the 100-pin TQFP form factor. Confirm moisture sensitivity level handling requirements during assembly. Check current lifecycle status and availability through authorized distributors.

Memory IC Selection Notes

Select this component when a system requires high-speed, non-blocking concurrent access to shared memory resources. The 45 ns access time suits moderate-speed asynchronous interfaces. Consider the 100-pin TQFP package constraints for board space. Evaluate power consumption profiles against system thermal limits, noting the standby mode capabilities.

Memory IC Part Context

The 7025 series represents a family of high-speed dual-port SRAMs designed for complex digital signal processing and communication applications. These devices facilitate efficient data exchange between processors without bus contention. The 7025L45 variant specifically targets applications needing reliable, low-latency memory access within standard TTL-compatible voltage levels.

Memory IC Replacement Considerations

Cross-reference part numbers such as IDT7025L45PF8 or other 7025 series variants with matching 45 ns speed grades and 100-pin TQFP packages. Verify pinout compatibility and electrical specifications before substitution.
