Microcontrollers are highly integrated computer systems on a chip:a processor and various support functions such as program memory,discrete I/O, A/D converters, serial communications, counter/timers,and watchdog timers are normally integrated in the same chip.
They are the key component for software-based data acquisition and simple controlling applications giving a higher flexibility and autonomous capability versus pure hardware solutions. They are widely used in many spacecraft subsystems and applications such as:
The following block diagram is an example of Microcontroller for space applications; It is a SPARC based microcontroller derived from a reduced version of the LEON2-FT processor core.
