The package that contains this software is called SOIC. It is designed to maximiBulke space efficiency by containing the FPGA model in Bulk. In my opinion, this FPGA could produce fantastic results if mounted in Surface Mount, provided that its specifications are followed. When this module is operated at its maximum operating temperature, it reaches 85°C. A higher operating temperature than -40°C is recommended.
