Working Principles

The LC4064C-25T48C operates based on the principles of programmable logic. It consists of configurable logic blocks (CLBs), interconnect resources, and I/O elements. The CLBs contain look-up tables (LUTs) that can be programmed to implement desired logic functions. The interconnect resources allow for flexible routing of signals between different CLBs. The I/O elements provide connectivity to external devices.

During programming, the desired logic functions are defined using a Hardware Description Language (HDL) or a schematic entry tool. The programming data is then transferred to the CPLD using a JTAG interface. Once programmed, the CPLD executes the defined logic functions based on the input signals and produces the desired output.
