Working Principles

The LC4384B-35TN176C operates based on the principles of programmable logic. It consists of an array of configurable logic blocks interconnected by programmable interconnects. These logic blocks contain look-up tables (LUTs), flip-flops, and other components that can be configured to implement desired logic functions.

During programming, the user defines the desired logic functions using HDL, which is then compiled into a bitstream. This bitstream is loaded into the CPLD, configuring the internal logic blocks and interconnects accordingly. Once programmed, the device operates autonomously, executing the defined logic functions.
