<p><h3>Embedded - CPLDs (Complex Programmable Logic Devices)</h3>Complex Programmable Logic Devices (CPLDs) are a category of integrated circuits composed of configurable logic gates that offer higher speeds, lower power consumption and greater density than conventional Programmable Logic Devices (PLDs). They can be used to implement combinational and sequential logic designs. The LC4128B-5TN100C (LC4128B) is a CPLD that consists of 536 programmable logic cells (CLC), 100 macrocells and 15,360 bits of embedded RAM. <h3>LC4128B-5TN100C application field and working principle</h3>The LC4128B-5TN100C CPLD is an effective and economic single-chip solution for low-medium density of logic designs. It is commonly used in consumer and industrial applications such as automotive, communication, consumer electronics, medical devices and power supplies. In consumer products, the LC4128B-5TN100C CPLD is often used for controlling product operation, integrating functions of a system, and implementing control and logic algorithms.The main processor of LC4128B-5TN100C CPLD is the logic array block (LAB). The LAB consists of CLCs. Each CLC contains a set of programmable elements that can be configured to implementany arbitrary logic function. For example, a CLC can be configured with a half-adder, multiplexer, register, or flip-flop. The CLCs are connected together using dedicated interconnects.The macrocells provide further logic blocks and support more complex logic designs. Macrocells are more powerful than CLCs. Each macrocell contains configurable logic and registers. The registers store information while the logic can be configured to implement a variety of algorithms. The LC4128B-5TN100C CPLD has 100 macrocells and 15,360 bits of embedded RAM. The LC4128B-5TN100C CPLD also supports Glue Logic for connecting logic blocks together. Glue Logic is used to provide connections between logic devices which are not accessible from the dedicated interconnects or available from the pre-defined logic blocks. It is also used to simplify complex logic designs by minimizing the connection between logic blocks.The LC4128B-5TN100C CPLD is programmed using a dedicated programming language such as Verilog, VHDL, or the new SystemVerilog language. By programming the logic blocks and configuring the interconnects, the LC4128B-5TN100C CPLD can be used to implement a wide range of logic designs. By using the LC4128B-5TN100C CPLD, designers can create complex and powerful designs in a matter of seconds, while maintaining high levels of speed and low power consumption. The LC4128B-5TN100C CPLD is an ideal solution for low-medium density of logic designs in consumer and industrial applications. </p>
