As the brain of the application, the MCU typically consumes the most power and has the most control over the system power consumption. As with all designs, it is important for the designer of a low-power embedded system to consider trade-offs between power consumption, and other factors, such as cost, size and complexity.
Microcontrollers, which are complete computers incorporating the processor, RAM, ROM and I/O ports into a single package, are often employed in an embedded system because of their low cost, small size, and low power requirements. Figure 1.1.1.
Power management is an essential aspect of low-power systems and embedded development. Therefore, it is necessary to understand the power management integrated circuit (PMIC) concept when planning to build IoT systems.. A PMIC is a type of integrated circuit (IC) designed to manage power in components of electronic devices.

Low Power Design Basics 2 Because every application is different, systems designers will have a tendency to weight some of these elements more than others. For example, some applications such as water meters spend most of their time in a standby state so clearly their long duty cycles require very low standby power consumption.
Many emerging applications such as the internet of things, wearables, and sensor networks have ultra-low-power requirements. At the same time, cost and programmability considerations dictate that many of these applications will be powered by general purpose embedded microprocessors and microcontrollers, not ASICs.
