Embedded computers are widely used in a variety of fields, from industry control and robotic automation to gaming and entertainment systems. Programmable logic devices (PLDs) are a type of embedded computer technology used in many devices that require complex logic. One type of PLD is the Complex Programmable Logic Device (CPLD), and one specific CPLD that is commonly in use is the EPM7096LC84-15. This article provides an overview of the application field and working principle of this CPLD.

The EPM7096LC84-15 CPLD is commonly used in digital television equipment, such as set top boxes, satellite receivers and digital recorders. It is also used in a variety of consumer, commercial and industrial applications, such as industrial control, automated test equipment and automation systems. This CPLD is also used in automotive applications, including fuel systems, security systems and entertainment systems.

The EPM7096LC84-15 CPLD features complex logic in a single integrated circuit. It contains 7,096 programmable logic circuits (macrocells) split across four logic blocks, which can all be configured using fuse programming. This configuration allows for easy and efficient integration of logic functions, resulting in improved system performance, cost savings and ease of use.

The EPM7096LC84-15 CPLD works on the hierarchical logic principle. This means that rather than having one large, complex circuit with all of the logic functions built-in, the CPLD is split into several layer of logic blocks. Each logic block has its own individual functions, which are combined and combined again in the outer layer to produce a single overall result.

In the EPM7096LC84-15 CPLD, the four logic blocks are divided into three different tiers. The outermost layer is the fourth tier, and it consists of programmable logic gates. This layer combines all of the logic from the three lower tiers, resulting in the overall output of the CPLD. The three lower tiers each have internal logic functions, and each partly consists of XOR and XNOR logic. The first tier consists of logic functions called macrocells, which each contain a small application-specific logic block and a flip-flop. The second tier consists of combinatory logic gates, and the third tier Adders. Each of these three tiers has its own set of flip-flops and counters, which also contribute to the overall result.

Overall, the EPM7096LC84-15 CPLD is a highly flexible and efficient device that is widely used in digital television equipment, consumer and commercial devices, industrial control systems and automotive applications. It is based on the hierarchical logic principle and has four logic blocks configurable using fuse programming. Each logic block consists of macrocells, combinatory logic gates and adders with integrated flip-flops and counters. The combination of these features enables the CPLD to provide complex logic functions in a single integrated circuit.
