System-on-chip — a chip integrating core clusters, GPU, NPU, memory controller, modem, and peripheral blocks onto a single die or package.

System-on-chip — a chip integrating core clusters, GPU, NPU, memory controller, modem, and peripheral blocks onto a single die or package.

Examples: Apple M-series, Qualcomm Snapdragon, NVIDIA Orin.

Dominates mobile and edge computing — tight integration reduces latency, power, and board area.

Vs. discrete MPU + discrete designs.

SoC Cortex-A ⟶ high-end smartphone processors (Snapdragon, Apple M1)

SoC Cortex-M ⟶ very smart sensors.

ESP32 as SoC: sensor + MCU + radio + antenna; could communicate by itself (floating dark box), but needs electricity ⟶ power ⟶ PCB + capacitors.

General-purpose like MCU: can be a toaster, a drone, a watch.
