Embedded technologies have been around for many years, particularly in applications that require consistent, high performance, and reliability. CPLDs (Complex Programmable Logic Devices) are one of the more recent advancements in embedded technology. A CPLD is an integrated circuit (IC) that can be programmed to perform logic functions, replacing hundreds of discrete logic components with a single IC. One such CPLD is the Altera LC4064C-5T48C. In this article, we will discuss the application fields and working principles of this IC.

Key Features

The Altera LC4064C-5T48C CPLD features 5K logic elements, up to 64 macrocells, and 48 I/O pins. It runs at a 40 MHz frequency and has an uncompressed access time of 10 ns with a very low power consumption of 230 mW. It is ideal for applications that need consistent, high performance and low power consumption. It also supports clock speeds up to 100 MHz and offers an extended temperature range, making it suitable for embedded applications with harsh environmental conditions.

Application Fields

The Altera LC4064C-5T48C CPLD can be used in a variety of applications, including communications and networking, industrial automation, automotive electronics, digital gaming, consumer electronic, and medical device design. These CPLDs are ideal for applications requiring a high degree of integration, such as integrating multiple digital systems into a single system, or providing sophisticated protection systems for industrial applications.

The Altera LC4064C-5T48C CPLD can also be used in military and aerospace applications. Its robust architecture and high-reliability make it an ideal choice for designs that may require radiation, temperature, and other harsh environmental conditions. It is also capable of accelerating system performance, providing high data rates for signal integrity, and minimizing design costs and risks.

Working Principle

The Altera LC4064C-5T48C CPLD uses logic elements and I/O buffers to implement logic functions. Each logic element consists of two input pads, two output pads, and two input/output pads, which allow the logic element to be connected to other logic elements. The logic elements are connected via structured programming logic, which allows it to perform sophisticated logic functions. The I/O buffers, on the other hand, provide the link between the logic element and the outside world. They allow the logic element to communicate with and control other devices.

The Altera LC4064C-5T48C CPLD can be programmed using the Altera Quartus II development software. This software allows the designer to compile a design into an Altera Native PFS File, which is then loaded into the CPLD. Once loaded, the CPLD will act according to the programmed logic functions, providing the desired functionality.

Conclusion

The Altera LC4064C-5T48C CPLD is a versatile, high performance integrated circuit that can be used in a variety of embedded applications. Its sophisticated logic elements, I/O buffers, and integrated programming software make it ideal for applications that require a high degree of integration and high levels of performance and reliability. By understanding the application fields and working principles of this IC, design engineers can easily incorporate it into their designs.
