GAL16V8D-15LJN

The GAL16V8D-15LJN is an embedded Complex Programmable Logic Device (CPLD) developed by Lattice Semiconductor. It is a medium-density CPLD for space-constrained designs, providing 8 programmable I/O pins, 16 logic blocks, and built-in support for an in-system configuration (ISC) feature. The GAL16V8D-15LJN supports up to 8 macrocells, allowing designers to considerably reduce their chip count without sacrificing flexibility. It also supports a wide range of technologies, making it highly versatile and applicable in a broad range of application fields.

The GAL16V8D-15LJN is ideally suited for low- to medium-density embedded applications such as industrial, automotive, security, and communications. Its extremely small package size, nominal power requirements, and integrated features makes it ideal for designs whose architecture can benefit from a CPLD. For example, it can be used to replace costly and complicated designs with flexible logic implementations. This makes it especially attractive for cost-sensitive designs where high density and low power are essential.

The GAL16V8D-15LJN is designed to be an in-system programmable (ISP) device, making it an ideal choice for quick prototyping or updating designs in an off-the-shelf environment. It also features an asynchronous reset signal, ensuring reliability and high performance. Additionally, the device features a unique power management system, allowing it to maintain high performance in various operating temperature ranges.

The GAL16V8D-15LJN is implemented on a 3k cell-array architecture, achieving its low- to medium-density design goals. It also possesses a deterministic delay, meaning that the device can be configured to a specific timing requirement. This feature makes it ideal for designs that require a fast response time.

The GAL16V8D-15LJN’s working principle is a combination of two key components, logic gates and memory cells. Logic gates operate on a predetermined set of binary states and control the flow of digital circuits. Memory cells are used to store information that is required by the CPLD. This allows the CPLD to remember the programmed parameters it needs to perform its intended task.

The GAL16V8D-15LJN is programmed using software written in Verilog or VHDL. These tools provide the designer with a graphical interface which allows them to define the flow of the programming language. From the interface, they can enter the desired logic operation and memory contents, allowing them to create the desired functionality.

In summary, the GAL16V8D-15LJN is an excellent embedded CPLD for various application fields. Its small size, relatively low power, integrated features, and asynchronous reset signal capabilities make it a great choice for low- to medium-density designs. Furthermore, its support for various technologies and memory cells makes it an ideal solution for applications requiring deterministic delays.
