Embedded - CPLDs (Complex Programmable Logic Devices)

The EPM7128SLC84-15 is an example of a Complex Programmable Device (CPLD). A CPLD is a programmable logic device that aggregates many logic elements and usually supports a wide range of memory, I/O and logic functions, making it a good fit for use in embedded applications. It is often used to replace custom logic chips, where flexibility and/or size constraints dictate that a programmable solution is necessary.

Application Field

The EPM7128SLC84-15 is suitable for a wide range of applications, such as digital signal processing, memory and I/O control, firmware design and storage, communications, and motor control. It is particularly suitable for use in embedded applications with its small size, low power consumption, low voltage operation, and wide range of logic functions.

For example, it can be used in robotic control systems, where it can provide a compact solution for analog-to-digital conversion and motor control. The CPLD can be programmed to sense the environment and control the motors accordingly. It can also be used in medical electronics, where it can enable complex algorithms to be quickly implemented. In the automotive industry, CPLDs can be used to improve the efficiency of systems such as anti-lock brakes and stability control.

In addition, the EPM7128SLC84-15 can be used for communication systems, such as cell phones and wireless networks, because of its built-in logic functions, fast access times, and low power consumption. It can also be used as a controller in industrial machinery and equipment, such as printing equipment and 3D printers.

Working Principle

The working principle of the EPM7128SLC84-15 is straightforward. It combines logic elements, I/O and memory blocks in a single device. The programmer defines the desired logic functions by mapping the desired logic onto the CPLD. By programming the CPLD, it is possible to create complex and flexible logic functions in a very small form factor.

The EPM7128SLC84-15 is programmed using a programming language such as Verilog or VHDL, which is then compiled into a bitstream. The bitstream is then used to program the CPLD and set up the desired logic functions. In addition, the EPM7128SLC84-15 also supports in-system programming, where the CPLD can be programmed without the need for external programming hardware.

Once programmed, the EPM7128SLC84-15 is capable of performing complex operations, such as implementing sequential and combinational functions, memory and I/O operations, and implementing bus protocols. The CPLD is also capable of routing and combining signals, making it suitable for high-speed data processing, routing, multiplexing, and synchronization.
