XC18V01PC20C Description

The XC18V01PC20C is a 1Mb (128K x 8) serial configuration PROM manufactured by AMD, designed for storing configuration data for FPGAs. This In-System Programmable (ISP) memory operates within a 3V to 3.6V supply range and supports a 0°C to 70°C operating temperature range, making it suitable for industrial and commercial applications. Housed in a 20-pin PLCC (Plastic Leaded Chip Carrier) package, it features surface-mount compatibility and complies with ECCN 3A991B1B2 and HTSUS 8542.32.0071 for regulatory adherence. Though marked as obsolete, it remains relevant in legacy systems requiring reliable FPGA configuration storage.
