Additional Details

The XC18V04-VQ44C is programmed using the industry-standard JTAG (IEEE 1149.1) interface, allowing for in-circuit programming without the need to remove the device from the board. This simplifies the design and debugging process. The device is ideal for applications where quick configuration and low power consumption are critical. The non-volatile memory ensures that the FPGA configuration is retained even when the power is removed. Data is transferred serially during the configuration process. The device is also RoHS compliant.
