The goal is to have an energy source that outputs the microcontroller’s required current and voltage. While microcontrollers can often be powered by a direct or alternating current, for added security, many developers use external batteries to support necessary functions.
Additionally, batteries enable devices to go cordless. A device that doesn’t need to be plugged into a wall can be more easily transported. When using current microcontroller battery technology, there are certain limitations because a battery can only provide so much power for so long.
Each BBU module employs a main microcontroller and a battery management system (BMS) microcontroller. For Analog Devices’ reference design, the MAX32690, an ultra low power Arm ® microcontroller, acts as the main microcontroller and is responsible for six important processes (see Figure 1).
CPU processor: The processor is the microcontroller’s command center. It handles all the instructions that direct function in the device. This could mean performing basic operations and transferring data to communicate commands with the rest of the system. Memory: There are two main memory types in a microcontroller—program and data memory.
Microcontrollers cannot function without a power supply. They have no built-in battery, meaning they are powered with external sources. The goal is to have an energy source that outputs the microcontroller’s required current and voltage.
Peripherals: Input and output devices make up the interface between the processor and the rest of the world. Input ports take information in and convert it to binary data for the processor. That data is then output to other devices that execute a variety of tasks. A microcontroller is essentially a mini-computer on a single chip.
