Introduction of MCU Chip
What is MCU chip
MCU, full name is Microcontroller Unit, is a kind of computer integrated on the same chip. It usually includes CPU, memory (such as RAM, ROM) and other peripheral interfaces (such as timer, serial interface, analog-to-digital converter, etc.) Due to its compactness and low power consumption, MCU is mainly used in embedded systems and Internet of Things devices.
Main Composition of MCU Chip
