Introduction to Embedded CPLDs

Complex Programmable Logic Devices (CPLDs) are a type of integrated circuit that includes multiple programmable logic arrays or look-up tables that can be configured to perform a variety of tasks. CPLDs are mainly used in embedded applications and are typically found in industrial, automotive, networking, and consumer electronic applications.

CPLDs are easily programmable, so the device can be used in a wide range of different applications. Additionally, some CPLDs can be designed to execute instructions, making them powerful processors for embedded applications. CPLDs are also often used to substitute parts of a system that require multiple discrete components as they can reduce the system’s complexity and cut down on the number of components needed.

LC4512B-75FTN256C Application Field and Working Principle

The LC4512B-75FTN256C is a CPLD chip from the Lattice Corporation family of integrated circuits. It is a 512 macrocell device, meaning there are up to 256 individually configurable logic blocks, each providing two sets of 4-input Boolean function blocks and two 16-bit product term registers. The LC4512B-75FTN256C supports up to 2 million logic gates in a single device and is an output-enabled device.

The LC4512B-75FTN256C is suitable for a wide range of embedded applications, including: Automotive, Digital Consumer, Industrial, Medical and Networking applications. It can be used to replace a variety of discrete components, making it suitable for applications where multiple components would normally be required. Additionally, it is compatible with both high and low voltage designs, making it suitable for use in various embedded system designs.

In terms of its working principle, the CPLD is programmed using programmable logic devices (PLDs) or, more commonly, FPGAs. Each of the individual components in a CPLD are programmable using these devices and can be configured to execute specific instructions. For example, in an automotive application the CPLD may be programmed to execute instructions of controlling the fuel injectors. The configuration of the components in the CPLD is stored in specialized battery-backed memory.

When a signal is sent to the CPLD, each one of the programmable components within it will be activated, depending on the particular configuration stored. This will cause a particular or set of outputs or functions to be performed. In some CPLDs, this may include running memory or instruction-executing control units. Additionally, some CPLDs can also be used to program FPGAs, extend their functionalities or execute complex logic operations.

Conclusion

Overall, the LC4512B-75FTN256C CPLD is an ideal solution for embedded applications, as it can be used to reduce system complexity and cut down on the number of components required. The device can also be used to program FPGAs in order to extend their functionalities.
