Embedded - CPLDs (Complex Programmable Logic Devices) have wide applications in many industrial and consumer applications. GAL20V8C-10LJN is a type of CPLD that has been used in a wide variety of applications. This article will discuss the application field and working principle of GAL20V8C-10LJN.

The GAL20V8C-10LJN is a 20-pin CPLD. It is a low-cost programmable logic device (PLD) with an array of programmable logic blocks and an associated output buffer register. It has 5 input pins, 8 input/output pins, 8 output pins, and 5 general purpose I/O pins. It is well suited for applications requiring logic testing, logic viewing, logic simulation and design verification.

The GAL20V8C-10LJN is used in a variety of applications, including embedded computers, data acquisition systems, automotive electronics, aerospace and military equipment, communications and networking, consumer electronics, factory automation, and medical equipment. It is also used in industrial and process control, test and measurement, and instrumentation applications. The GAL20V8C-10LJN is well suited for applications where high reliability, flexible design, and low cost are important.

The working principle of GAL20V8C-10LJN is based on a logic array having an output buffer register. The logic array contains five logic blocks, each with 32 programmable logic cells, two 4-bit registers, two 5-bit programmable multiplexers, and two 8-bit registers. Each logic block is coupled to a five-bit address decoder. The output buffer register is a 16-bit register. It is used to store the outputs of the four logic blocks. The output buffer register is also used to store the current state of the logic device.

The programming of GAL20V8C-10LJN is performed by programming the logic array and the output buffer register. Programming the logic array involves specifying the logic equations for the logic cells and the logic blocks. For each logic block, the logic equations for the logic cells and the logic blocks are specified by writing the appropriate numbers into the appropriate addresses. The output buffer register is programmed using the same programming techniques used for programming the logic array.

In summary, GAL20V8C-10LJN is an embedded CPLD that has a wide range of applications in various industries. Its working principle is based on a logic array and an associated output buffer register. It is programmed by specifying the appropriate logic equations for the logic cells and the logic blocks. The GAL20V8C-10LJN is a cost-effective and reliable solution for applications requiring programmable logic devices.
