The IDT7130SA90P is a high-speed, asynchronous Dual-Port Static RAM (SRAM) manufactured by Renesas Electronics (formerly IDT). This device provides simultaneous, independent access to a common memory location from two separate processors or controllers, making it suitable 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 (90ns)
• 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 IDT7130SA90P typically has a memory organization of 1K x 8 bits. It operates from a single 5V power supply and is commonly found in a plastic DIP package. The device has separate address, data, and control lines for each port, which allows fully independent read and write operations. The interrupt flag facilitates data availability signaling between the two ports.
