What is a CPLD?
Before delving into Lattice Semiconductor CPLDs, it is essential to understand what CPLDs are and how they differ from other programmable logic solutions. A CPLD is a type of programmable logic device that uses a matrix of programmable logic cells and interconnects to implement digital logic circuits. CPLDs are used to implement small to medium-sized digital circuits that require moderate to high-speed operation. What is The Lattice Semiconductor CPLD Unlike FPGAs that are designed to implement complex digital designs, CPLDs are designed to implement simpler designs.
CPLDs can be programmed to implement specific logic functions
Their programming is non-volatile, meaning that they retain their programmed state even when power is removed. CPLDs offer several advantages over other programmable logic devices such as ASICs, FPGAs, and microcontrollers. CPLDs have lower power consumption, lower cost, and faster development time. CPLDs also have faster turnaround times compared to ASICs, which require long lead times for design and fabrication. CPLDs are ideal for applications that require fast time-to-market, low power consumption, and moderate logic capacity.

In addition to the specific features of each family of CPLDs
Lattice Semiconductor also offers several features across its CPLD product line. These features include:
- Non-volatile programming: Lattice Semiconductor CPLDs use non-volatile programming, which means that the devices retain their programmed state even when power is removed. This makes them ideal for applications where power may be lost or interrupted, such as automotive or industrial systems.
- Low power consumption: Lattice Semiconductor CPLDs are designed for low power consumption. The devices have standby currents of less than 10 µA, which makes them ideal for battery-powered applications.
- High-speed operation: Lattice Semiconductor CPLDs operate at high speeds, with some devices operating at up to 225 MHz. This makes them suitable for applications that require fast signal processing or high-speed communication.
- High reliability: Lattice Semiconductor CPLDs are designed for high reliability. The devices have built-in error detection and correction, and they are tested to meet industry standards for reliability.
- Easy programming: Lattice Semiconductor CPLDs are easy to program using the company’s ispVM System software. The software supports graphical design entry, allowing designers to easily create digital circuits using a graphical interface.
Comparison with other programmable logic solutions
CPLDs are just one type of programmable logic device, and they have several advantages over other programmable logic solutions, including ASICs, FPGAs, and microcontrollers. ASICs are custom-designed integrated circuits that are created for a specific application. ASICs offer high performance and low power consumption but require long lead times for design and fabrication. CPLDs, on the other hand, offer faster development times and lower costs, making them ideal for applications that require fast time-to-market.
FPGAs are similar to CPLDs in that they are programmable logic devices.
However, FPGAs are designed for larger logic designs and offer more flexibility than CPLDs. FPGAs can be reprogrammed to implement different logic functions, and they offer higher performance than CPLDs. However, FPGAs also consume more power and cost more than CPLDs.
Microcontrollers are small, integrated circuits that include a CPU
memory, and I/O peripherals. Microcontrollers are ideal for small embedded systems that require low power consumption and moderate processing power. CPLDs offer faster processing speeds than microcontrollers and can be used to implement specific logic functions that may not be available in a microcontroller.
Lattice Semiconductor CPLDs offer a low-power, low-cost programmable logic solution for a variety of applications. With features such as non-volatile programming, high-speed operation, and high reliability, Lattice Semiconductor CPLDs are an excellent choice for embedded system designers looking for a flexible, easy-to-program logic solution. CPLDs offer several advantages over other programmable logic devices such as ASICs, FPGAs, and microcontrollers, making them ideal for applications that require fast time-to-market, low power consumption, and moderate logic capacity.
