memory, and input/output devices, microcontrollers make it
economical to digitally control even more devices and processes.
Mixed signal microcontrollers are common, integrating analog
components needed to control non-digital electronic systems.
Some microcontrollers may use four-bit words and operate at
clock rate frequencies as low as 4 kHz, for low power consumption
(milliwatts or microwatts). They will generally have the ability to
retain functionality while waiting for an event such as a button press
or other interrupt; power consumption while sleeping (CPU clock
and most peripherals off) may be just nanowatts, making many of
them well suited for long lasting battery applications. Other
microcontrollers may serve performance-critical roles, where they
may need to act more like a digital signal processor (DSP), with
higher clock speeds and power consumption.
