Low end micrcontrollers optimize low-power, manufacturing process support for analog blocks and flash memory and low cost per each square milimeter of silicon

Low end micrcontrollers optimize low-power, manufacturing process support for analog blocks and flash memory and low cost per each square milimeter of silicon for low transistr count designs. You can best achieve all these using old manufacturing processes so moore's law really doesn't apply. Following Moore's law tends to optimize $/transistor and low power consumption for high transistor count devices.
