Embedded – CPLDs (Complex Programmable Logic Devices) are becoming a very popular solution in automation and real-time applications. The GAL18V10B-20LJ is one example of a CPLD, which provides an efficient way to integrate a number of integration functions into a single package. This article will discuss the application field and working principle of the GAL18V10B-20LJ.

Application field: The GAL18V10B-20LJ can be used in a wide range of applications, including automotive, industrial, aerospace, and medical. It is suitable for applications that require fast switching and accurate timing, as well as single-function or multi-function logic. The device can be used to implement a variety of logic functions such as multiplexers, counters, flip-flops, and arithmetic operations. It is also suitable for memory and peripheral interfacing.

Working Principle: The GAL18V10B-20LJ is a programmable logic device (PLD) that uses programmable read-only memory (PROM), which is electrically programmable, for logic control. The PROM can store up to 8K bits of information, with each bit corresponding to one logic gate. The device also has macrocells – logic gates with pre-defined functions. The GAL18V10B-20LJ is also reversible, meaning that it can be programmed to perform a different set of functions after it has been programmed. Additionally, the device features an array of I/O pins and multiple power supply options.

The GAL18V10B-20LJ is composed of two types of logic: combinatorial logic, which performs logic functions based on the current inputs, and sequential logic, which performs logic based on the current inputs and the output states of previous clock cycles. The device is programmed using a computer with EPROM programming software. The programming software takes a program in a high-level programming language, such as C++, and converts it into a set of logic commands that are stored in the device’s memory.

The logic implemented by the GAL18V10B-20LJ is controlled by a predetermined set of instructions, which can be customized to perform a wide range of tasks. The device can be programmed to perform multiple operations at once, making it ideal for applications such as motion control and process automation. The GAL18V10B-20LJ can also be used to develop embedded systems, such as digital signal processors, by distributing logic functions among multiple stages of processing.

The GAL18V10B-20LJ is an efficient and versatile PLD, which can be used in a wide range of applications. Its relatively small size and low power consumption make it an ideal choice for small and medium-scale applications. With its vast array of features and ability to be programmed, the GAL18V10B-20LJ offers an excellent solution for embedded designs.
