What is 32-bit microcontrollers?

32-bit microcontrollers are small, low-power computers on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. The '32-bit' refers to the data bus width and the size of registers that the microcontroller uses, enabling it to handle larger data chunks and more complex operations compared to 8-bit or 16-bit microcontrollers. They're commonly used in embedded systems for applications requiring moderate processing power, such as industrial control, automotive systems, consumer electronics, and IoT devices. Their advantages include higher performance, greater memory addressing capabilities, and better support for complex algorithms compared to their smaller counterparts.
