Embedded - CPLDs (Complex Programmable Logic Devices) are widely used in a variety of applications ranging from automotive systems, medical devices to industrial control systems. The LC4128V-5TN144I is an example of this type of device, and is often used in controls, communications, and instrumentation applications. In this article, we will look at the application field and working principle of the LC4128V-5TN144I.

The LC4128V-5TN144I is a high-density 32 macrocell reprogrammable device with a 4K-bit non-volatile EEPROM configuration capable of volatile programming. It offers a wide range of features, including low power consumption, small package size, high performance in system-level testing, and superior JTAG performance. It is suitable for design initiatives in the automotive, aerospace, industrial, communications, computing, and consumer markets.

In terms of its application field, the LC4128V-5TN144I can be used for a range of projects, such as embedded controllers, industrial automation, LED lighting and display, power conversion and control, automotive systems, home entertainment, embedded audio, and advanced system management. The device also features low-power operation, making it suitable for battery-powered applications. It also features high clock rate and low setup/hold times, making it suitable for use in high-speed applications.

The working principle of the LC4128V-5TN144I is based on the concept of programmable logic devices (PLDs). Specifically, the device consists of a number of configurable logic blocks (CLBs) and a fixed logic structure. Each of the CLBs consists of programmable logic array (PLA) configurations, which are used to implement a range of different logic functions. The fixed logic structure includes a clock generator, global reset logic, and configuration logic, which provides access to the user for controlling the basic device functions. The user is also able to customize the CLBs within the device through software programming.

The device uses a classic four-stage pipeline system to process the input data and generate the corresponding output data. It works by first latching the data from the input into a register. The register is then read by a combinational logic module. The logic module generates the output data based on the input data and a set of predefined logic rules. Finally, the output data is latched into a register and outputted to a driving circuit. The driving circuit then transfers the output data to the outputs.

Overall, the LC4128V-5TN144I is a powerful and feature-packed PLD device that is suitable for a wide range of applications. It offers low power consumption, small package size, high performance in system-level testing, and superior JTAG performance, making it ideally suited for embedded control, industrial automation, LED lighting and display, power conversion and control, automotive systems, home entertainment, and embedded audio-related projects. Furthermore, its four-stage pipeline system works efficiently and reliably to process the input data and generate the corresponding output data.
