LTC2668CUJ-16#PBF Overview
In the 40-WFQFN Exposed Pad package, you will find it. In order to operate it, a voltage supply of 15V volts is required. Surface Mount-connectors can be used to attach this FPGA module to the development board. The SoftSpan™ Series is one of the types of FPGAs that belong to this type. As far as the operating temperature is concerned, it should be kept within 0°C~70°C when operating. Unlike other FPGA models, this one is contained in Tube for the sake of space saving. 40 terminations are present in total. You can find related parts by using the part number LTC2668, which is its base part number. In order to make it work, 40 pins have been designed. With a total of 40 pins, it is equipped with a high level of security.
