Embedded - CPLDs (Complex Programmable Logic Devices) are components of hardware designed to perform digital computation. They are often used to reduce the complexity and cost of a digital system or provide a specific solution to an embedded application problem. The most common type of CPLD used in embedded applications is the LC4128V-5TN144C. This CPLD is designed to minimize the design time and wiring complexity associated with digital applications and provides a low cost, high performance solution.

LC4128V-5TN144C is a powerful programmable logic device which can combine high speed, low power and flexibility. It is powered by an Altera low-power Flex 10K family architecture, specifically the EP1S25Q240C6, providing up to 7.5 K logic elements and 6 Megabits of dedicated RAM for fast clock rates and quick state response, and hence it can serve several purpose. This device combines the performance of a dedicated ASIC with the flexibility of a programmable logic device. Its single-chip configuration reduces board-level wiring, especially in large and complex systems.

As an embedded device, LC4128V-5TN144C can be used in a variety of applications, such as automotive, medical and consumer devices, power distribution control systems, industrial automation control, and digital signal processing. This CPLD provides a low cost solution with its 25,000 programmable logic elements, 16 Xilinx IOs, 14 IOs, and four high-speed 10K elements, capable of running up to 150 MHz clock frequency. This structured architecture minimizes design complexity and provides a cost effective solution for implementing digital systems. Additionally, it integrates many digital circuits and allows quick prototyping.

In terms of working principle, the LC4128V-5TN144C device is an asynchronous design, which means it can cycle through instructions with varying speeds. It uses an architecture which is made up of a series of data-flow cells, which process and transfer data to the output cell. The input cells select the data to be processed and load it into the data-flow cells. The data-flow cells assess the data in order to perform operations and transmit the results to the output cells. The output cells take the results from the data-flow cells and direct them to the appropriate components in the system. On the other hand, the clock tree is used to synchronize the data-flow cells. This is done by providing a reliable clock source at the top of the tree and then deskewing it towards the bottom of the tree in order to set the same clock frequency and timing for all of the data-flow cells.

Overall, the LC4128V-5TN144C embedded CPLD is an efficient, cost effective and low power device for digital systems. It offers high levels of programmability, flexibility and speed, and is suitable for large and complex systems. Its intuitive design and automated set-up simplify the design process, providing a small form-factor solution for a variety of embedded applications.
