Detailed explanation-1: -1. Which of the following should a microcontroller at-least should consist of? Explanation: A microcontroller at least consists of a processor as its CPU with RAM, ROM, I/O ports and timers. It may contain some additional peripherals like ADC, PWM, etc.
Detailed explanation-2: -A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM.
Detailed explanation-3: -The program of the microcontroller is stored in the memory. There are two types of memory: RAM (Random Access Memory) which can read and write data, and ROM (Read Only Memory) which mainly stores programs as read-only data. There are various types of RAM and ROM depending on the usage.
Detailed explanation-4: -Nearly every microcontroller consists of five main components: the CPU, RAM, Digital Converters, Serial Bus Interface, and Input/Output ports.
