XC3S400-4TQ144I Overview
A 144-LQFP package contains it, and it is available for download. There are FIELD PROGRAMMABLE GATE ARRAY transistors in this type of FPGA. Its 97 I/Os help it transfer data more efficiently. A fundamental building block contains 8064 logic elements or cells. Power is provided by a 1.2V-volt supply. The Surface Mount-slot connector on the FPGA module can be connected to the development board. Fpga chips operates at a voltage of 1.14V~1.26V and uses a battery to supply power. FPGAs belonging to the Spartan®-3 series are a type of FPGA that belong to the Spartan®-3 series of FPGAs. Operating temperatures should be maintained within the -40°C~100°C TJ range at all times when the unit is in use. During the installation of this device, 97 outputs were incorporated. A model of this FPGA is contained in Bulk for the purpose of saving space. In total, there are a total of 144 terminations on fpga chips. Having a RAM bit size of 294912 means that this device will offer you a lot of memory. A significant amount of RAM is allocated to this FPGA module to ensure that the program can operate normally. This cable has 144 pins and is designed to connect to a computer. 896 LABs/CLBs are integrated into this FPGA. With a 1.2V supply voltage, designers can fully utilize the flexibility of the device.
