There are two packages that contain it: 28-VFQFN Exposed Pad, CSP package and X package. In this case, the FPGA part belongs to the Data Converter ICs family. An attachment Surface Mount allows the FPGA module to be attached to the development board. The AD5674 series FPGA is a type of FPGA that belongs to the AD5674 family of FPGAs. When operating the machine, it is important to keep the temperature within -40°C ~ 125°C range. There is an FPGA model contained in Tray in order to conserve space. This device has a pin count of 28 in it. The device package supplied by 28-LFCSP (4x4) is one of its suppliers.
