Detailed explanation-1: -The correct answer to Microcontrollers often has CPUs, RAM and ROM.
Detailed explanation-2: -In 1981, Intel introduced an 8-bit microcontroller called the 8051. It was referred as system on a chip because it had 128 bytes of RAM, 4K byte of on-chip ROM, two timers, one serial port, and 4 ports (8-bit wide), all on a single chip.
Detailed explanation-3: -Most microcontrollers have some amount of internal RAM, commonly 256 bytes, although some microcontrollers have more and some have less. For example, the PIC18F452 microcontroller has 1536 bytes of RAM, which should be enough for most microcontroller-based applications.
Detailed explanation-4: -CPU (Central Processing Unit). RAM (Random Access Memory). ROM (Read-Only Memory). Internal Oscillator (the main timer of the MCU). I/O (Input/Output) Ports. Peripheral Controller Chips (other optional accessories and components).
