LTC2657IUFD-L12#PBF Overview
This package is included in the 20-WFQFN Exposed Pad package and is available for purchase. 3V volts power it. Using a Surface Mount connector, you can mount this FPGA module on the development board. In order to ensure a safe and efficient operation, it is important to maintain a temperature within -40°C~85°C at all times. Using the Tube layout, this FPGA model can be contained in a very small amount of space. The total number of terminations is 20. Parts related to this part can be found using its base part number LTC2657. The device is designed with 20 pins in total. It is possible for this FPGA to perform as per its specifications as long as it is mounted in Surface Mount direction. It is powered by a 3/5V battery, which can be purchased separately. The device has a total of 20 pins on it. In addition, it is able to support a maximum supply voltage of 5.5V. The unit is capable of working with a minimum supply voltage of 2.7V.
