The XC1704LVQ44I is a Configuration PROM (Programmable Read-Only Memory) manufactured by Xilinx. This device is primarily used to store the configuration data for Xilinx Field-Programmable Gate Arrays (FPGAs). When an FPGA powers up, it loads its configuration from an external memory device, and the XC1704LV series serves this function. This particular model comes in a VQ44 package, indicating its physical form factor and pinout.

Applications:

• Configuration storage for Xilinx FPGAs
• Bootstrapping embedded systems
• Storing firmware or other critical data
• Industrial control systems
• Telecommunications equipment
• Aerospace and defense applications

Features:

• 4 Mbits of storage capacity
• Low-voltage operation (LV)
• Fast access time
• In-system programmability
• Q44 package (Quad Flatpack, 44 pins)
• Non-volatile storage
• Multiple device cascading for increased storage

Benefits:

• Reliable configuration for Xilinx FPGAs, ensuring proper operation.
• Reduced system complexity by providing on-chip configuration storage.
• Easy to program and reprogram, allowing for design flexibility.
• Low power consumption, suitable for battery-powered applications.
• Small footprint due to the Q44 package.
• Secure storage of critical data, protecting against unauthorized access.

Additional Details:

The XC1704LVQ44I is a critical component in many Xilinx FPGA-based systems. It's designed for robust and reliable operation in a wide range of environments. The 'I' suffix typically indicates an industrial temperature range. The device is programmed using a standard FPGA programmer. The data is retained even when power is removed, making it suitable for applications where configuration persistence is required. The exact programming procedure and timing specifications can be found in the Xilinx datasheet for the XC1704LV series. The cascade feature enables the connection of multiple PROM devices to support larger FPGA configurations. The low voltage characteristic allows it to integrate into modern low-power systems.
