The XC1765EJC is typically programmed using a Xilinx-compatible PROM programmer. The programming process involves loading the configuration file into the device. Once programmed, the PROM is connected to the FPGA. Upon power-up, the FPGA automatically loads the configuration from the PROM. The non-volatile nature of the device ensures that the FPGA is always correctly configured. The 'EJC' package often specifies a particular operating temperature range and package style (e.g., PLCC, SOIC) appropriate for various applications. It is essential to check the datasheet for the specific characteristics of the 'EJC' package to ensure compatibility with the target application environment.
