5 Questions
What is the main difference between a microcontroller and a microprocessor?
The main difference is that microcontrollers are designed for embedded applications, while microprocessors are used in personal computers or other general purpose applications consisting of various discrete chips.
What kind of memory is often included on chip in a microcontroller?
Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is often included on chip, as well as a small amount of RAM.
How are microcontrollers different from system on a chip (SoC)?
In modern terminology, a microcontroller is similar to, but less sophisticated than, a system on a chip (SoC). An SoC may include a microcontroller as one of its components, but usually integrates it with advanced peripherals like a graphics processing unit (GPU), a Wi-Fi module, or one or more coprocessors.
In what kind of products and devices are microcontrollers commonly used?
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems.
What is the advantage of using microcontrollers in device design?
By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes.
