Embedded - CPLDs (Complex Programmable Logic Devices) are integrated circuits that are designed to implement a set of combinational logic elements to control data flow and transfer signals between different components of a system. The GAL18V10B-10LJ is an example of such a device, which is used in a wide range of applications. This article will discuss the application field of the GAL18V10B-10LJ and its working principle.

Application Field

The GAL18V10B-10LJ is a programmable logic device with 18 macrocells and macrocell outputs, designed to reduce the size and complexity of designs. It is commonly used in applications such as digital signal processing, video systems, and control systems. These devices are suitable for applications such as communications systems, instrumentation, industrial control and point-of-sale systems. Since it is a programmable device, it can be used to replace the current components in the system and can be used to upgrade the system\'s performance and features. It can also be used to implement complex communication protocols, which are not possible with other available solutions.

Working Principle

The GAL18V10B-10LJ consists of 18 macrocells, which are the basic building blocks for programmable logic devices. Each macrocell contains a number of combinatorial logic and flip-flop elements including a function generator, programmable and/or configurable logic cells, data and carry logic, output multiplexers, macrocell output and clock logic, and an asynchronous reset circuit. All the macrocells are connected to each other in a hierarchical manner, allowing the device to be programmed to implement complex functions with little or no additional circuitry.

The data input to the device is multiplexed, sequenced and latched before being fed to the macrocells. This input data is then analyzed, processed and stored in the macrocells. Product terms within each macrocell are then combined to create the output data. The output data is then multiplexed to generate the system\'s output. The device can be programmed and reprogrammed using a programming machine, which can be done in the field or at the factory.

In summary, the GAL18V10B-10LJ is an embedded programmable logic device with 18 macrocells, suitable for a variety of applications. It is programmed and configured to implement complex logic functions, using the macrocells and their interconnections. It can be used to reduce the complexity of a system, create upgrade paths and improve performance.
