XC17256EJI from Xilinx Inc. is a configuration PROM used to store startup data for compatible FPGA designs, making it a practical choice in systems that require reliable non-volatile configuration memory. Devices in this category are commonly used in industrial controls, communications hardware, embedded computing, and legacy programmable logic platforms where dependable boot configuration is important. Engineers typically select configuration PROMs like this for established FPGA architectures that need a dedicated, deterministic configuration source rather than a general-purpose memory device. For maintenance, repair, and long-life support programs, this part can also be relevant when sustaining existing fielded equipment. The current lifecycle status for XC17256EJI is information not available, so design teams should verify product status directly with the manufacturer or authorized sources before committing to new production. RoHS compliance information is also not available in the provided data and should be confirmed through official documentation before procurement or compliance sign-off.
