Yes, but you don't need many smarts to send a few bits to configure a PLL
You can get low end microprocessors in 8 pin packages. They don't even need
an external clock or crystal, just a bypass cap. If you are concerned about
noise, they can go into deep sleep mode. Most of them have really low power
modes designed so that the battery for a chip can run close to shelf life.
These are my opinions. I hate spam.
