The IDT7130LA70JI is a high-speed 1K x 8 Dual-Port Static RAM (SRAM) manufactured by Renesas Electronics America (originally by Integrated Device Technology, IDT). This device features two independent ports, each with its own address, data, and control lines, allowing for simultaneous and asynchronous access to the memory array from two different sources. It's designed for applications requiring shared memory between processors, controllers, or other digital systems.

Applications

• Multi-processor systems: Shared memory for inter-processor communication and data exchange.
• Digital signal processing (DSP): Data buffering and synchronization between DSPs and other system components.
• Image processing: Frame buffer memory for image capture and display systems.
• Networking: Packet buffering and queuing in network switches and routers.
• Industrial control: Data logging and control in industrial automation systems.

Features

• Dual-Port architecture: Allows simultaneous and asynchronous access from two independent sources.
• 1K x 8 memory organization: Provides 1024 bytes of storage, organized as 1024 words of 8 bits each.
• High-speed access time: 70ns access time ensures fast data transfer.
• Low power consumption: Reduces overall system power requirements.
• Independent control signals: Each port has its own address, data, and control lines, providing flexibility in system design.
• Interrupt Flag: Indicates when data has been written to an empty location or read from a full location.
• Output Enable control: Allows disabling the outputs for bus isolation.
• Available in various packages: including Ceramic DIP.

Benefits

• Efficient Data Sharing: Enables fast and efficient data sharing between multiple processors or systems.
• Increased System Performance: Reduces communication bottlenecks and improves overall system throughput.
• Simplified System Design: Simplifies the design of multi-processor systems by providing a shared memory resource.
• Reduced Latency: Provides low-latency access to shared data.
• Flexibility: The dual-port architecture and independent control signals provide flexibility in system design.

Additional Details

The IDT7130LA70JI provides two independent ports (Port A and Port B) each with its own address inputs, data I/O, and control signals (Chip Enable, Output Enable, Write Enable). Each port can access any memory location independently and simultaneously. The 70 in the part number indicates the access time in nanoseconds. The JI indicates the package type, which in this case is a Ceramic DIP package. The device operates from a single 5V power supply. The operating temperature range is typically -55°C to +125°C.
