7025L45PF

Memory IC Overview

The Renesas Electronics Corporation 7025L45PF is a dual-port static random-access memory (SRAM) integrated circuit. It provides a storage capacity of 131,072 bits organized as 8K words by 16 bits. The device features an asynchronous parallel interface with a maximum access time of 45 nanoseconds. It operates within a supply voltage range of 4.5V to 5.5V and is housed in a 100-pin Plastic Quad Flat Package (TQFP).

Memory IC Feature Summary

• Dual-port architecture enabling independent simultaneous access from two distinct processors or systems.
• Integrated hardware arbitration logic to manage bus contention during concurrent read/write operations.
• Supports semaphore and interrupt flag functions for efficient multi-processor synchronization.

Memory IC Applications

• Multi-processor system architectures requiring shared memory resources.
• High-speed data buffering in telecommunications equipment.
• Industrial control systems utilizing dual-CPU redundancy schemes.
