Yes, I used FPGA for some projects, also saves external hardware sometimes. https://panteltje.nl/pub/FPGA_board_with_25MHz_VCXO_locked_to_rubidium_10MHz_reference_IMG_3724.GIF As to 'multitasking' in small micros costing 3 US dollars or less, for some of those microchips running at many MHz using a chip for each task is also an option. I build a LED controller here that uses 3 Microchip PICs to drive red green and blue LED 'disco lights', music coming from a PC via ethernet. https://panteltje.nl/panteltje/pic/ethernet_color_pic/index.html
