The microcontroller is present in all devices that are meant to interact and connect to a computer in order to facilitate communication. It is programmed to perform certain tasks for the other hardware. FPGA, which stands for Field Programmable Gate Array, is a circuit integrated that can have millions of logic gates, which can be configured electrically to carry out some tasks.
FPGAs have a kind of nature that makes them be more flexible when compared to most microcontrollers. You can reprogramme the FPGA device to carry out some logic tasks that fit into its number of gates. The logic gates of the FPGA can be required so as to obtain the desired task.
Microcontrollers are restricted to perform certain tasks as there is already a laid down set of instructions or circuitry that must be followed by the programmer in writing code. FPGAs are known to consume more power the microcontrollers.
