Expensive hardware FPGAs are significantly more expensive than microcontrollers, which can be sourced at a fraction of the cost, regardless of production scale. Since they're application-specific, ASICs are expensive to produce in small quantities but are far more cost-effective than FPGAs in mass production.

What Is an FPGA? Field Programmable Gate Arrays (FPGAs) are integrated circuits often sold off-the-shelf. They're referred to as 'field programmable' because they provide customers the ability to reconfigure the hardware to meet specific use case requirements after the manufacturing process.

The process of choosing an FPGA is like any other decision-making process in our life. First you look inside to collect all the requirements for your project, and then you weigh your requirements by importance. For example, if the most important issue is cost, that might make some FPGAs more appealing than others.
