Which one of the following offers CPUs with integrated memory and peripheral interfaces?
Multiple Choice Options
- A
Memory system
- B
Embedded system
- C✓ Correct Option
Microcontroller
- D
Microprocessor
Detailed Technical Solution & Explanation
A microcontroller is a single-chip computer that integrates a CPU core with on-chip memory (RAM, ROM/Flash) and peripheral interfaces (GPIO, UART, SPI, I2C, ADC, timers, PWM). This integration makes microcontrollers ideal for embedded applications where a complete computing system is needed in a small, low-cost package.
Examples: Arduino (ATmega328P), PIC16F877, STM32, ESP32.
Option Analysis:
•
Option A (Memory system): A memory system is a collection of memory devices — not a CPU with integrated peripherals.
•
Option B (Embedded system): An embedded system is a complete application (hardware + software) — it may use a microcontroller, but it's not the chip itself.
•
Option C (Microcontroller): ✅ Correct. A microcontroller integrates CPU, memory, and peripheral interfaces on one chip.
•
Option D (Microprocessor): A microprocessor is CPU-only — it requires external memory and peripheral chips.
