Microcontrollers, microprocessors, and FPGA (Field-Programmable Gate Array) modules are fundamental components in embedded systems and digital electronics. Microcontrollers are integrated circuits that combine a processor core with memory and peripheral interfaces, suitable for applications requiring low to moderate computational power and real-time control. Microprocessors are standalone processing units designed for higher computational tasks in general-purpose computing devices. FPGA modules are reconfigurable logic devices that allow designers to implement custom digital circuits and algorithms, making them versatile for prototyping and specialized applications. Generally, microcontrollers are more affordable than microprocessors and FPGA modules due to their integrated design and targeted applications. Microprocessors can range from budget-friendly options to high-performance processors with advanced features, impacting their prices accordingly. FPGA modules' prices depend on factors like logic capacity, speed grade, and additional features such as integrated peripherals or connectivity options.
