GAL16V8D-15QJ application field and working principle

Introduction

GAL16V8D-15QJ is a Complex Programmable Logic Devices (CPLD) developed by Lattice Semiconductor Corporation. It is based on the Generic Array Logic, a programmable logic device that uses a fuse-BLOW programming algorithm and provides 8 inputs, 8 outputs and 200PLD logic elements. The chip is also designed to provide predictable and efficient switching performance and low power consumption suitable for cost-sensitive applications.Because of its low cost, CPLDs are widely used in embedded applications, for example, applications requiring a programmable logic device such as microcontrollers, DSPs, FPGAs, and ASICs.

Application Field

GAL16V8D-15QJ is typically used in applications requiring a low cost, low power Programmable Logic Device (PLD) to facilitate design complexity. It is used for a variety of purposes, ranging from simple function implementations to complex logic functions. Common applications include Interface logic, Gauss algorithms, signal processing, communications, microprocessors, FPGAs, and ASICs.For example, it can be used in industrial automation, such as motor control, programmable logic controllers (PLC) and Programmable Automation Controller (PAC). It can be used with proximity sensors to monitor speed, position, and other critical performance parameters. It can be used to monitor and control process equipment, industrial robots, and actuators. GAL16V8D-15QJ can also be used to control watering schedules for gardens and automated irrigation systems. In addition, GAL16V8D-15QJ can also be used in consumer electronics, such as watch timepieces, home theatre systems, digital video and audio devices, motor control, and LED lighting systems. In home appliances, powerful GAL16V8D-15QJ can be used to programme washing machines and ovens, as well as to enable sophisticated remote monitoring and control of temperature, humidity and other parameters.Since GAL16V8D-15QJ is available in an industry-standard, standard package, it can be easily combined with other devices to simplify designs and reduce system costs. It can be combined with an external processor or microcontroller, or used in a stand-alone mode, allowing for flexible and cost-effective development.

Working Principle

GAL16V8D-15QJ is a PLD device based on the Generic Array Logic architecture. It consists of 8 inputs, 8 outputs, 200 PLD logic elements and two multiplexers for a total of 160 logic gates or flip-flops. It operates with 3.3V power, uses an asynchronous programming algorithm and provides a wide operating temperature range.The working principle of GAL16V8D-15QJ is based on Fuse-BLOW technology. It has a small amount of memory, which allows it to store programming information, such as the Circuit Design Library (CDL) or EDIF files. When the Fuse-BLOW programming algorithm is used, a programming voltage is provided to each of the logic elements of the device, and a controlled current is then sent through the elements. This creates a hot spot, melting metal in the logic element, leading to the reprogramming of the device.The advantage of this method is that it can be used to implement small and cost-effective designs, while providing predictable and efficient switching performance. The GAL16V8D-15QJ is a high-density CPLD device that provides a low cost and low power solution for embedded applications. It is a reliable, predictable and efficient logic device which can be used to implement an application’s design. It is easy to use and configure, and its customizable parameters can be easily programmed, making it a cost-effective solution for a wide range of applications.
