The Xilinx XC1765EJI is a high-density, in-system programmable Read-Only Memory (PROM) configuration device. It is specifically designed to store the configuration data required for Xilinx Field-Programmable Gate Arrays (FPGAs). This PROM guarantees that the FPGA is configured quickly and reliably upon power-up, enabling immediate operation of the target system. The 'EJI' suffix likely indicates a specific package type and temperature range.

Applications

• Configuration storage for Xilinx FPGAs used in data processing equipment.
• Boot memory for embedded systems that necessitate non-volatile program storage.
• Data storage in industrial automation equipment needing reliable startup routines.
• Aerospace and defense systems requiring dependable configuration memory.
• Automotive control applications needing fast and reliable initialization.

Features

• In-System Programmable: Simplifies reprogramming without needing to remove the component.
• High Density: Provides 64k bits of storage, accommodating complex FPGA configurations.
• Fast Configuration: Rapidly configures the FPGA upon system power-up.
• Non-Volatile Storage: Data is preserved even when power is off.
• Enhanced Endurance: Supports many reprogramming cycles for prototyping and development.

Benefits

• Streamlined FPGA Configuration: Supplies a clear method for setting up Xilinx FPGAs.
• Reduced Development Time: Allows quicker design iterations and debugging due to in-system programmability.
• Improved System Reliability: Assures the FPGA is properly configured each time the system boots.
• Cost-Effective: Decreases the necessity for extra memory devices.
• Increased Design Versatility: Compatible with various FPGA setup configurations.
• Optimal System Performance: Minimizes system startup delay through fast configuration times.

Additional Details

The XC1765EJI commonly uses a serial interface to load the configuration data into the FPGA. Programming is generally done with a Xilinx programmer device. Please refer to the Xilinx datasheet for precise electrical specifications, timing diagrams, and programming steps to ensure correct use and long-term reliability. The Package type is likely a JLCC (J-Leaded Chip Carrier).
