Following table-1 mentions difference between Microcontroller and FPGA.

Specifications Microcontroller FPGA
Principle of operation Desired program is flashed in the microcontroller which executes instruction consecutively. It works based on software program. Desired program to hardwire the logic circuit of FPGA is loaded. Based on this logic FPGA works as desired.
Software Programming Language used C, C++, C# etc. VHDL, Verilog
Application Suitable to be used for serial execution of instruction. Here speed is proportional to execution time of the instruction. It is used for parallel execution.
Processing power It is time limited. The execution depends on processor cycling power. It is space limited. More is the work, more is the logic circuits required to be created on FPGA chip.
Components needed All the required components are sufficiently available on chip itself. No external components are needed unless for specific requirements. It requires RAM, ROM and external storage. Almost most of the FPGA boards come up with these components in order to have rapid prototype developments.
