A 12-TSSOP (0.118, 3.00mm Width) package contains it, and it is available for download. FPGA modules can be attached to development boards using a Surface Mount-connector. It is necessary to keep the operating temperature within 0°C~70°C when the device is operating. Unlike other FPGA models, this one is contained in Tube for the sake of space saving. In order to find related parts, you can use its base part number LTC2644.
