MCU and CPU Architectures in Embedded Devices

What powers your embedded device? It all comes down to the MCU/CPU architecture.

✅ MCU (Microcontroller) = CPU + memory + peripherals on a single chip
✅ CPU (Core) = the brain that runs instructions
✅ Cortex-M series → real-time, low-power control (M4, M7)
✅ Cortex-A series → high-performance, runs OS like Linux
✅ The right choice balances power, performance, and cost

Know your architecture → write better code, design smarter systems.
