The XC3S400-4FTG256C is an IC (Integrated Circuit) component designed by Xilinx Inc. It belongs to the Spartan-3 FPGA (Field-Programmable Gate Array) family and offers a range of features and capabilities. Here is an overview of the key features of this component:
1. FPGA Architecture: The XC3S400-4FTG256C is based on the 90nm CMOS process technology, which provides a good balance between performance and power consumption. It features a hierarchical SRAM-based architecture, which allows for efficient implementation of complex digital systems.
2. Logic Cells: This IC component contains 40,960 logic cells, also known as slices, which are the fundamental building blocks of the FPGA. These logic cells can be programmed to perform various logic functions, such as AND, OR, XOR, and more complex operations.
3. Look-Up Tables (LUTs): Each logic cell in the XC3S400-4FTG256C contains a 4-input look-up table (LUT). These LUTs allow for the implementation of combinatorial logic functions. They can be cascaded to create larger LUTs to support more complex logic operations.
4. Block RAM: The IC component includes 864 Kbits of block RAM, which can be used as configurable memory elements or for data storage purposes. This block RAM can be divided into multiple independent instances, providing flexibility in designing memory-intensive applications
