In order to meet the requirements of wireless communication and wireless network nodes, the implementation of smaller volume, extremely low power consumption, lower price, wireless system-on-chip (SOC) has been rapidly developed in recent years, this wireless system-on-chip microcontroller, memory, A\/D converter and the required interface circuit and wireless data communication transceiver chip all integrated into a very small chip. The emergence of a single chip, which can constitute an independent wireless communication and wireless network node (also known as wireless MCU), provides a new choice for the development of wireless communication and wireless network, but also makes the design of wireless communication and wireless network more simplified and easier to develop.
