The IDT7130SA45J is a high-speed, low-power, asynchronous Dual-Port Static RAM (SRAM) manufactured by Renesas Electronics (formerly IDT). This device allows independent, simultaneous access to a common memory location from two separate processors or controllers. This feature makes it ideally suited for inter-processor communication and data buffering applications.

Applications

• Inter-processor communication in multiprocessor systems
• Data buffering and data sharing between different system components
• Image processing and video applications
• Network buffers and data switches
• High-speed data acquisition systems

Features

• Asynchronous dual-port operation
• Fast access time (45ns)
• Low power consumption
• On-chip address decoding
• Interrupt Flag for port-to-port communication

Benefits

• Increased system performance through parallel data access
• Simplified system design by eliminating arbitration logic
• Reduced power consumption, suitable for portable applications
• Improved data throughput in communication systems

Additional Details

The IDT7130SA45J typically has a memory organization of 1K x 8 bits. It operates from a single 5V power supply and is available in a ceramic DIP package. The device features separate address, data, and control lines for each port, allowing completely independent read and write operations. The interrupt flag provides a mechanism for signaling data availability between the two ports.
