CPUs and architecture

Which LSI integrates a CPU, memory and peripherals such as timers and ADCs on one chip and is used to control appliances and equipment?

  1. AGPU
  2. BMicrocontroller (MCU)
  3. CHBM
Show answer and explanation

Answer: B. Microcontroller (MCU)

A microcontroller integrates, besides the CPU, flash memory for programs, working RAM, timers, ADCs, communication interfaces and more on one chip. It is used to control all kinds of equipment, including appliances, cars and industrial machinery, and is shipped in very large quantities.
