Embedded - CPLDs (Complex Programmable Logic Devices)

The LC4128ZE-7TN144C is a complex programmable logic device (CPLD) in the LC4000 family of devices. It is a powerful, low-cost, high-performance device that utilizes the latest technology to provide high density, low power consumption, high performance, and a low cost and reliable telecommunications solution for market applications. It has 144-pin TQFP package and requires a 3.3V single-ended power supply.

Application Field

The LC4128ZE-7TN144C CPLD is widely used in the fields of telecommunications, consumer electronics and automotive electronics. It is used for switching and routing large amounts of data and can also be used for timers and minute tasks like generating interrupts, rebooting systems, controlling memory and performing small tasks. In consumer electronics, it can be used for digital signal processing solutions, such as audio, video, and TV data. In automotive electronics, it is used as a switch and selector, and can be used to control and secure access to data. It is also used in industrial applications such as control of pumps and motors.

Working Principle

The LC4128ZE-7TN144C has 32 macrocells, each consisting of a look-up table (LUT) and a flip-flop. The LUTs consist of two 2-input AND gates, a 3-input AND gate and a 3-input OR gate, which can be configured to perform a wide range of combinational functions. The output from the LUT is then passed to the flip-flop whose output is used as the output for the macrocell. The internal logic of the CPLD is composed of pre-programmed logic blocks, which are programmed to realize the desired logical functions. Through the programming interface, the user can configure the macrocells to perform the required logic. The programming is done with a chip programming device or software such as Xilinx ISE.
