Processors & Compute
What is MPU?
Microprocessor
A microprocessor (MPU) is a processor that relies on external memory and typically runs a full operating system like Linux, suited to devices needing rich UIs, networking, or heavier compute than a microcontroller.
The line is blurring, but the rule of thumb holds: reach for an MPU when you need Linux, a display stack, or significant processing; otherwise an MCU is cheaper and lower power.
